Attempted to make a keto burger and fries last night. It wasn't a total success, but part of it was.
The bun was based on an almond flour recipe and I didn't really like it. It wasn't that it tasted bad, just that it didn't taste or have the texture of a hamburger bun. It was moist and dense, almost like a cake. In fact I think I want to try that recipe again and add some flavorings for a keto sweet treat. Seems like it would be good for that.
The fries were really good though. I used jicama instead of potatoes. I started out using a recipe involving baking them in the oven, but I have a deep fryer to I just decided to wing it. Jicama is a lot more resistant to cooking than potatoes, so after cutting the jicama into strips, I boiled the strips for about 20 minutes, then dryed them off thoroughly and deep fryed them in coconut oil until they were golden brown. These were really good, if a bit labor intensive.
