Anna, I haven’t tried making this bread without the vinegar, so I don’t know for sure how the recipe would fare without it. Vinegar here is used not only for the right flavor, but also to react with the leavening agent and create the proper rise for the bread. If you take out the vinegar, you’ll need to replace it with another acid. Can you tolerate lemon juice? If so, I’d try this recipe using 2 to 3 teaspoons of fresh lemon juice in place of the vinegar. Let me know how it goes if you give it a try! https://www.youtube.com/watch?v=VExW4SNt3Ko
I just made this today, and my husband, toddler, and I all loved it! We used ours for cheese and tomato sandwiches, and my husband managed to eat about half of the loaf before it even cooled. Like another person mentioned, I had to bake mine longer, but for me it was nearly twice as long (I’m at a relatively high altitude, maybe that’s why?). As yet another person said, it will now be a staple in our home too!
For example, although white potatoes were recorded as being available during the Paleolithic era, they are usually avoided on the Paleo diet because of their high glycemic index. Processed foods are also technically off limits due to an emphasis on fresh foods, but some Paleo diets allow frozen fruits and vegetables because the freezing process preserves most nutrients. https://www.youtube.com/watch?v=J0GYdEX6lqQ
