I found as I was making these that I had no cream of tartar so I substituted an equal amount of baking soda (since I really had no idea how to fix it). I also decided to mix the dough up in the food processor since I am basically lazy. Made improperly, the flavor was pretty good but they were far too crumbly. I think they might be really good as the base for a breakfast cheese biscuit sandwich (heated with melted cheddar in the middle).
Ooooh boy, these are delicious biscuits. Easy to make, too. I love Stilton cheese. So glad to have tried this recipe, thanks for posting.
