13 - Cooking in the Oven

To start cooking, use several sticks of kindling to build a fire on the firebrick lip of the oven, where the bricks jut out in front.

Once the fire is going, use a long wood-handled instrument to shove the fire inside the oven -- we use a grass whip. It doesn't matter exactly what you use, but it needs to be long enough to stick into the back of the oven while keeping your hands well outside the oven, and it can't have a metal handle because it would get too hot to hold -- you'll be using it to shove glowing embers around.

You'll need to keep tending the fire constantly for about 30 minutes, feeding it more kindling and shoving the embers around to all parts of the oven (firebrick) floor. We recommend drinking beer and yakking with a friend while doing so.

We stuck a cheap (high-temp) metal thermometer
inside the oven in order to get the hang of gauging the temp of the oven. The numbers burned off the thermometer after a few fires, but now we know that after about 30 minutes, it's about 750 degrees, and it's ready for pizza!

Use the grass whip to push all the glowing embers/wood to the outer edges of the oven, forming a ring of fire and distributing the embers as evenly as is reasonable.

Use a short, damp-but-not-wet rag mop* to swipe the firebrick surface at center of the ring; that's where your pizza is going to go, and a quick swipe with the rag mop will keep the bottom of the crust from getting too ashy.

Meanwhile, at the pizza-construction operation, put about 3 tablespoons of dry corn meal on top of the peel and spread it evenly over the surface of the peel. Then -- and only then! -- put the pizza crust on top of the peel. Add toppings according to your favorite recipe, and take the pizza out to the oven, where your firetender has been faithfully feeding the fire.

Hand the uncooked pizza on its peel to the firetender. Standing with the peel between the lip and the center of the oven, the firetender gently shakes the peel so the pizza can be rustled on to the firebrick as close to the center of the oven as possible.

With the temp at 750 degrees, the pizza only takes about 2 minutes to cook, so be ready to pull that thing out of there and get it to where the hungry people are.

There's definitely a flow to this process, and you'll get the hang of it as you use your oven. We often use pizza night as an excuse to socialize with a small crowd (or vice versa), so coordinating the steady flow of pizzas can be tricky. What we've found works best is:

An hour before eating:
  • prep pizza dough if making it from scratch; make enough crust for approximately one medium pizza per person
  • prepare toppings (dice veggies, shred or slice cheese, cook meat toppings, etc.) -- our friends and kids like to be put to work at this stage
30 minutes before eating:
  • firetender leaves to go do his/her thing at the oven
  • kitchen manager divides up dough and forms/tosses crusts -- this is kind of tricky, and your guests may not be able to get this right, so you'll either want to do it yourself or be prepared for some messed-up pizza
  • raw crusts are put on corn-meal dusted, movable surfaces (a pizza peel, a cutting board, corrugated cardboard, etc.)
  • each guest is assigned a raw crust on which to put the toppings of their choice. Don't let them pile the toppings too thick or the pizza will fall apart
5 minutes before eating:
  • The firetender rushes inside to say the oven will be ready in about 5 minutes
  • The first pizza is transferred from the movable surface to a pizza peel, and delivered to the firetender, who puts it in the oven for about 2 minutes.
  • Meanwhile, the second pizza is transferred to another peel, and delivered to the firetender at the oven.
  • The firetender removes the first pizza from the oven using the first peel, and a delivery person runs pizza and peel inside to the hungry crowd.
  • Meanwhile, the firetender uses the second peel to get the second pizza going. The firetender and the delivery person will alternate peels each time.

  1. Nice post! I'd want an oven like that. I grew up in the province during those years when an uncle put up a bakery and they

    had this large wood oven. As kids, we were allowed to shape our own bread from leftover dough which we would eat hot

    and fresh from the oven. :) :) Pizza Conveyor Ovens

  2. How long did it take you to make the oven, from start to finish? Did you take a break, I mean could you stop during any part of the process? I can see that building the base would be a labor of love, to find the stones. However, once you started with the clay, did you need time to allow it to dry? I have enjoyed reading your posts. Thank you for the information.

  3. Thank you for taking the time to post this. It is very clear and well written. Is the purpose of the 5 foot pit to allow for drainage? Or is that the frost line in vermont? It seems remarkably deep.

  4. Oh but wait! When did the straw go in?

    1. I asked myself the same question, but it must go into the adobe mixture as the fibrous material since according to Wiki: "Adobe (/əˈdoʊbi/, UK /əˈdoʊb/;[1] Arabic: الطوب) is a natural building material made from sand, clay, water, and some kind of fibrous or organic material (sticks, straw, and/or manure), which the builders shape into bricks (using frames) and dry in the sun."

  6. It’s great to bake pizza whenever you want in your own brick oven in your home. For as long as you have the ingredients with you, there’s no problem! ;) You can have a pizza party with your family or friends. That’s absolutely fun!

  7. Why so deep for the gravel pit? Also did the clay part need time to cure, Ive been wanting to make one of these for a couple of years, thanks very informative

    ReplyDelete
  8. I would love to make one of these. When do you make the hole larger in the front of the oven and when do you add the straw and why was the hole so deep? can this be used in the winter without fear of cracking?

  12. Wow - a fabulous idea and excellent, crystal clear directions. I'd love to do this - we also live on top of a huge rocky area - ex gold reef with filled in mines literally on our doorstep. Stones will be easily found on site - have to buy clay though - is artists clay OK to use??? Many thanks, Kate in Bendigo, Australia!!

    1. I'm not sure about artistic clay just make sure it doesn't have bentonite clay in it because it shrinks too much. Here's a good resource http://www.permies.com/t/1714/cob/cob-building-clay-isn-clay

  14. Wow this is very very impressive!!!!!! I have wanted one for years now and maybe now I can convince hubby and friends to build us one. we live in a log cabin in Santa Fe, TX in the country this would be perfect for me to make pizza & bread...
    Have you tried cooking anything else in your oven and if so what???
    I would love to be able to cook many things in it I guess you could by letting it cool to the right temperature of what your making.
    Thanks so very much for all your hard work and sharing it with us.. WISHING YOU GREAT SUCESS HAVE A BLESSED YEAR.. Linda & Robert and the 4 boys

    1. Hey Linda, I'm in Texas too and you'd be surprised how many places we have that do cob and adobe. There are workshops in Granberry and Houston. I'm not sure about Austin but I know there a cob homes there. You can make anything in a cob oven that you would in a regular wood burning oven. You can make a whole thanksgiving dinner in one.

  15. this is awesome. how well does it hold up in rain? how long have you had it, and do you need to do any repairs throughout the years?

    ReplyDelete
  16. Please do you have any (exploded drawings) of this wonderful oven? Is it a pedestal with an oven on top? How and where does the fire sit and exhaust and breath? Is the fire in the Pedestal and breath somehow through the rocks and somehow exhaust out the door of the oven? Can you put a cover on the oven for baking or is it best left open?
    In large font for old eyes, Please educate us.
    I adore this idea!

  17. Dave & Robin, thank you very much for sharing the detailed plans on building the Cob oven. Instructions were clear and easy to understand.

    All, there are a couple of questions as to what the five foot hole was for. My understanding is the hole was dug just to extract the clay. It serves no purpose beyond that and is why they filled it with gravel. I am under the impression that you don't even need to dig the hole if you are able to get clay from another source. Simply to avoid the eye sore of a pit of gravel, they built the cob oven right on top of the hole.

    I hope my observations help to clear the air. If I am wrong, please correct me. Thank you.

    Sincerely,

    John

    1. The gravel was for drainage. All cob structures need at least a foot or two of drainage under the foundation and a foundation of stone or brick built up at least a foot above ground to protect the integrity of the cob. They simply filled in the clay pit gravel instead of digging a new foundation site. Cob also needs a roof or protective coating like tadelakt to help protect it from the elements. The reason their oven cracked is because they forgot to put an insulation layer on the dome. You do this by putting a layer of cob on the newspaper then make about an inch thick layer of wood ash then another layer of cob to seal it in.

  18. The hole is to get below frost line. Straw would be used in an insulating layer over the thermal sand/clay layer. Besides adding strength more straw means more air pockets like the wine bottles

  19. Robin & Dave,

    Thank you so much for sharing your adventure in making a cob oven. You've done a great job in detailing the process, and adding some humor into it - though I, personally, think the ibuprofin should be listed with the oven materials - as it will be needed by us gramas& granpas when stomping the adobe and smashing fingers with the rocks.

    I have done much research myself, into the worlds of cob/adobe building, solar, hydro, tiny homes, and more - and your blog leaves me wishing that more I'd read had been done like yours!

    While I can not build the oven at this time, in the city where the landlord says 'no' to permanent structures ... your info will help me convince a friend or two to allow me to build a 'practice' oven or two at their homes!

    I am including some cob oven recipe links for everyone:

  20. Thanks for this very informative guide. So do you keep the wood-fuel burning inside the oven while you are cooking pizzas?

  26. Thank you for your very entertaining post. I have really enjoyed reading it. I am also building an Adobe/cob pizza oven and have followed a very similar process to you. I noticed that one of your other readers wanted to know what the straw was for. If you want to use your oven for more than pizza, you can add two more layers. The first one is made from a mix of mud and saw dust. This forms an insulation layer. The other layer is made from straw and mud. This is a sculptural layer that also holds the insulation together. Your oven will now retain heat for long enough to make beef, cook roasts and even a casserole.

  27. Thanks for the great post - very entertaining and helpful for someone considering building an oven.

    I have one technical question; you mention that you decided upon a 45" diameter oven, however the pictures seem to show that the fire brick pattern is 5 bricks wide. 5 x 4.5" per brick would be only 22.5". Can you clarify?

    Thanks

  28. Fantastic! Thanks for the info. I'm going to have a go at this in the summer. Ive got a corner of my patio where this would look great. I.m going to cheat a bit though, I'm going to use a cement mixer!

  29. it does not look that simple to build, but it is awesome, I would love to have one in my backyard, since I'm italian and i do make home made Pizza. Well done!

  32. Me and some friends have built one of these two years now at a 2 week camping event we all go to each year. We have to destroy it each year and build again. Site rules...no permanent structures. It's hard work, but to be able to bake while camping is worth every minute. We've even sourced our mud from the stream on site. We do have to add commercial clay to make it work better. Bread, cakes, brownies, pizza...YUM!!

  33. I love what I read, and I miss Vermont (grew up in Woodstock).
    questions:
    why do you need a deep pit? Could you build a base with a shallow (6") layer of concrete or cement, and then build the rock ring on that?

  34. Usually I make hangout with my friends into my house and outdoor and all of my friend loves to enjoy the wood fired pizza with me. I think I need a wood fired pizza oven to make pizza home or out door.
