When I first tried keto/low-carb recipes I started from scratch, searching out recipes online and buying all the ingredients: the almond flour, the sweetener, the extra butter, and so on. Then I found a couple of sites providing ready-mixed dry ingredients, and pretty much never looked back.
Everyone who's ever made that journey knows that eating low-carb isn't cheap, and you'd think that buying pre-mixed ingredients would be even more expensive that buying ingredients. My experience is that the mixes really aren't as dear as you might expect, especially when you take into account the time, the trial and error, the energy consumed, the sheer effort of getting a recipe to produce something edible. Mixes are the way for me now, and these biscuits are top of my list.
Tip: add a generous teaspoonful of ground ginger (or cinnamon, or whatever spice you like) to the dry mix in the bowl. Makes you feel that Christmas has come early!
I've always enjoyed biscuits, and went through a period of some years where I was eating sugar-free ones from Gullon and other suppliers, but those weren't helping with blood glucose control. Now my biscuit craving is satisfied and my glucose level doesn't spike nearly as much. A win-win!
