Mavis's Rise-Every-Time Sourdough Proofer & Dough Warmer
The dough warmer a 74-year-old bread champion designed herself — tall loaves, even in January
Mavis Lindahl, 74, has won 41 blue ribbons for her bread at the Minnesota State Fair. After 40 years of home-made proofing boxes she drew this one on the back of a class handout, and a small shop in Little Falls, Minnesota has built it to her drawing ever since. Her shoulder has ended her bread class, and these are the last warmers from her final run.
“Every box I built kept the air warm. The dough in the middle never got the message. So I drew what I actually needed: a flat plate, and a probe that goes into the dough.”
Mavis Lindahl · Alexandria, Minnesota
What you get
Walnut wood look with copper dial
Reads the temperature inside the dough
Switches itself off when time is up
Plus Mavis’s simple temperature tips
The four things Mavis wrote on the back of that handout
A thin steel probe goes right into the dough and shows its real temperature. “The outside of the dough lies to you. The middle never does.”
Set it anywhere from 70 to 120 °F and it stays within one degree. About 78 °F for bread dough, a little warmer for a sleepy starter.
The timer runs up to 24 hours, then the warmer switches off on its own. Set the dough at night, bake in the morning.
Mason jar, glass bowl or steel mixing bowl. Holds up to 4.7 quarts of dough, then fits in the cupboard.
Softens butter for rolls, keeps yogurt and kombucha warm, melts chocolate gently.
Turn the copper dial to set the temperature and the timer. Big, clear numbers on the display.
“I judged bread at the county fair for 30 years. Most flat loaves aren’t a bad recipe. They’re a cold kitchen. Dough rises best at a steady temperature, and in a Minnesota winter that is the hardest thing to give it. I could always tell a Mavis student. Their loaves stood up tall, and the last few winters they stood up tall in January too.”
Ardis Fjelstad · Longtime county fair bread judge · Douglas County, Minnesota
Perfect for
Why Mavis designed it exactly this way
- Steady warmth. Holds the temperature within one degree, all night long.
- No more guessing. The probe shows how warm the dough really is inside.
- Switches itself off. The 24-hour timer turns the warmer off when it’s done.
- Fits your bowls. Jars, glass and steel bowls up to 4.7 quarts.
- Small and tidy. About the size of a dinner plate, stores in a cupboard.
Bake with it in your own kitchen. If your bread doesn’t stand up a little taller, one email to info@countycraftco.com is enough for a full refund.
Good to know: Plugs into a standard US outlet (110 V). The warming plate is about 5 inches across, so very wide bowls will stand over the edge. That’s fine, but the dough rises best when the bowl sits flat on the plate. Always keep the probe in the dough, not in the air.

A note from the Tuesday night bread class:
In the winter of 1959, seven-year-old Mavis Lindahl watched her mother wrap the bread dough in her wedding quilt next to the wood stove on their farm near Alexandria, Minnesota. If the fire went out, there was no bread in the morning. Mavis went on to win 41 blue ribbons for her bread at the Minnesota State Fair, and since 1994 she has taught bread every Tuesday night in her church basement. For 40 years she built her own proofing boxes out of coolers, light bulbs and heating pads. In 2019 she drew what she actually needed on the back of a class handout, her son-in-law built the first one, and since 2022 a small shop in Little Falls has made them in small runs to her drawing. Her shoulder no longer lets her lift and knead, and her last class is on December 16. She turned down a kitchen store that wanted the whole box and is selling the last warmers herself, close to what she paid. 17 are left. When they are gone, there will be no more.

How is it made?
How is it made?
Mavis Lindahl designed this warmer, but she does not build it. After decades of home-made proofing boxes she drew it on the back of a class handout in 2019; her son-in-law Gunnar, a retired electrician, built the first working one, and since 2022 a small electrical shop in Little Falls, Minnesota has made them in small runs to her drawing. It is a flat warming plate in a walnut wood look with a copper-tone dial, a digital display, a 24-hour timer and a stainless steel probe that goes into the dough. It holds any temperature from 70 to 120 °F within one degree.
