The vinegar, when added last, gives the bread the rise. Often, Russian recipes call for baking soda and vinegar to give the rise (air pockets) you would normally get from yeast. I’m assuming, based on what I’ve read, that ACV has more health benefits, and a slightly different taste. I just took my bread out of the oven and it rose beautifully. Similar breads I’ve made called for less wet ingredients and were much denser. I can’t wait to cut this baby open and take a peek.
This bread does have quite a few ingredients, but you’ll find that most are staple paleo and keto pantry ingredients. In the list below you’ll find details on several ingredients and possible subs. But if possible, please do try and make this recipe without any subs. As out of the 18 permutations we tried, this one really was terrific and the absolute best.

thanks for the reply, but im still confused. the arrowroot you have pictured at the bottom of the recipe is the “flour” not the powder. I used the powder. however, it was hard to find and the only bottle of it that I could find was short of the 1/2 cup required in the recipe. I see you can buy larger quantities of the powder on-line. I added a TBSP of regular baking powder to make up for the short arrowroot powder. It came out pretty good!

I measured out all ingredients and microwaved on high for 90 sec. But I am pretty sure the problem was my microwave.. I own one of those flat-bed, inverter microwaves. It usually takes me 1:30 instead of 1:00 to heat up a cup of milk. So I guess I should have let the bread cook for longer. Does anyone have any experience with this sort of microwave?

These are AMAZING! I have celiac and was diagnosed about 4 months ago. It’s been very difficult and bread is what I miss most. Unfortunately, GF bread is not very tasty-i’ve tried a number of brands and have tried making my own. I love the simplicity of the recipe as well. Thank you for creating amazing clean recipes, your cookie bars are also fabulous!

Almond flour is often considered the “all purpose” flour of the paleo baking world. It’s used to make things like bread, cakes, and cookies with good results. The only caveat I have is that using almond flour alone can result in a dense baked good, so I typically use almond flour (or almond meal) in conjunction with arrowroot starch, tapioca flour, and/or flaxseed meal to lighten up the texture.
For instance, the fat allowance of the diet may be problematic. “My biggest hang-up with the paleo diet is all of the saturated fats it promotes with all of the meats,” explains Holley, noting that you could look for a locally sourced meat, whose origin and method of raising you're aware of, as a healthier option. Saturated fat from meat has been linked with an increased risk of early death. (9)

I made this for the first time today. I’m guessing here, but you may have mixed it too well, meaning the gas produced by the baking soda/yogurt/vinegar mixture was spent by the time you got it into the pan. No reaction means no gas, no gas means no lift. (I gently folded mine together and the rise brought it up above the top of the pan, just in the middle, but still.)

Food and Western Disease: Health and nutrition from an evolutionary perspective by Staffan Lindeberg (MD at Lund University in Sweden) is the newest book promoting the paleo diet. It covers the link between diet and disease in the Western world (all major diseases, including cancer, heart disease, obesity, stroke and dementia) and towards a greater knowledge of what can be defined as the optimal human diet. Benefits and risks are detailed. The Amazon reviews are all 5 stars. Especially read Susan Schenck's detailed review. You can read a preview at Google Books
I just made this bread and it came out great although I did adjust a few ingredients. I made this bread with four eggs(1 less than called for). Also I whipped the egg whites separately until they formed peaks(in order to make the bread less dense). Lastly, I added two tablespoons of applesauce to make up for the missing egg. This bread did take 45 minutes to bake, but I lowered the temperature to 245 because the outside was cooking faster than the inside. In the end this bread came out delicious and I enjoyed it with jam and honey, happy baking.
Meetup has a growing number of paleo groups, now numbering in the dozens. Each has a local message board. They have a map of Paleo Diet Meetups around the world. Initially I tried listing them all here. The number grew and Meetup wasn't letting me find groups in newest order, except for my zip code. You now have to go there to find the one nearest you.

Diet has been an important part of our evolution—as it is for every species—and we have inherited many adaptations from our Paleo predecessors. Understanding how we evolved could, in principle, help us make smarter dietary choices today. But the logic behind the Paleo diet fails in several ways: by making apotheosis of one particular slice of our evolutionary history; by insisting that we are biologically identical to stone age humans; and by denying the benefits of some of our more modern methods of eating.

If you have more questions on specific foods, we’ve included a comprehensive list of paleo diet foods below. We’ve provided a list of the foods that are allowed on the paleo diet. We’ve also broken this list down into the specific food groups, so you can see which meats, vegetables, fruits, nuts, and fats are on the paleo diet. In addition to all of that, we’ve also included a comprehensive list of foods not allowed on the paleo diet.
First things first. And this is of utmost importance. Woot Woot is STILL cool. Says me. Because I say it all the time, so it just HAS to be cool, right?! Wait, since I’m the most uncool person on the planet, you probably should stop saying woot woot immediately. 😉 Second, I had ZERO clue you used to be an almond butter-making maniac! Oh I wish I was your bestie during THAT fun phase of your life! Now you are just a no-bake brainiac! (<– see what I did there?). These bars are FAB, just like all the rest of your no-bake bars! They look super creamy and uber dreamy… and most dangerous, because who in the world could eat just one (or 5) of these babies?! SO GOOD! Pinned of course! Cheers, sweets! And haaaaappy Galentine's Day!! XOXOXOX
