Folding Design

Big enough to fit a large mixing bowl, several hand-shaped loaves, 2 gallons of yogurt, or your favorite 8 quart pot, yet easily folds flat (with rack and water tray stowed inside) for convenient and compact storage in a kitchen drawer. Add an accessory shelf for even more room.

Wonderful Bread!

"Love this product. When unfolded, I have plenty of room for my big bread bowl. When folded, it takes up very little space. The controlled temperature and humidity mean I get consistent results."  Garvin S., 04/11/2021

“The Brod & Taylor SAHARA Folding Dehydrator and the Folding Proofer and Slow Cooker are essential to what I do. I’ve used these tools nearly every day since I got them. If you’re at all interested in doing bread, fermentation, dehydrating, or just about anything interesting in your cooking, then you need to have these in your kitchen.”

Excellent to natural yeast

Folding Proofer & Slow Cooker Has fulfilled its purpose. I am satisfied with the product.

M. S.F.

I asked for my husband and son to buy this product for me for Mother’s Day. I had been contemplating buying it for a while, so this seemed like the perfect gift. We live in an old semi-detached home and it can be very tricky to find a good spot to proof my bread. Also, had tried making a sourdough starter before I received this proofer and nothing had happened (probably because the house gets too cold at night).

Now, with the consistent temperatures which I can set myself I have no problem proofing my bread, was able to successfully make the sourdough starter and then the sourdough bread and have used the slow cooker setting to make delicious homemade clotted cream (as we can no longer buy this in Canada).

Needless to say, I am thrilled with this product so far.

Folding proofer

I’m so glad that I purchased this folding proofer. It really made a big difference with my sourdough starter. I been making a lot of sourdough bread and this was the best investment that I did. It made so much easier for me. Thank you!!

Couldn’t be happier!

This is one of those things that’s so well engineered that unfolding it and setting it up is fun. It’s exactly the right size for most of my containers and bowls, and it’s completely silent.

The sourdough I make is more consistent and I’m not at the mercy of my apartment’s indoor temperature to get a good rise out of my dough.

I’m very happy that I got this!
