I have been keeping my carb down recently because my type 2 diabetes has gone a bit haywire and for the most part my snacks are cheese, almonds, sunflower seeds (not too many of them) and occasional berries. I miss biscuits and baked goods. I make a really good banana bread with high-fibre flour and artificial sweetener, and at Christmas I made sugar-free pavlova which was pretty good but everyone except DH refused to even try. Up until now those are the only things that have worked, everything else either tastes terrible or pushes up my blood glucose.
On Sunday I made brownies with black beans instead of flour and DH and I both tried them and they were horrible, they tasted of beans and the texture was soggy and just wrong. I was going to throw them out but put them into a container and left them overnight instead, and on Monday they were delicious. There was no bean taste, just chocolate, and they had gone fudgey in the middle and a bit crisp on the top. They are not as good as the proper brownies that I used to make with real chocolate and sugar, but they are still way better than you can buy in most shops. My cleaner was in today and I gave her a taste (I did warn her that it was made with black beans) and she inhaled a whole square and took a copy of the recipe.
So, my next challenge is crackers. I really miss them, especially Ryvita dark rye. Keto bread that you can buy is horrible and I haven't seen keto crackers anywhere.
