The way my French boyfriend and French roommate (both with Spanish grandmothers) pronounce the name, it does sound like "Monte Cows," or "monte cailloux." As far as I have been explained this cookie have resulted from a mix ofMuslim/Ottoman cuisine and Spanish cuisine; it's definitely not French. It is also affectionately referred to as a "poor person's cookie" because of its super-simple ingredients.
The recipe is a simple ratio of 3:2:1 -- 3 parts flour, two parts sugar, one part oil (we've used canola or peanut, both work well). We've used measuring cups or just regular mugs or even small bowls and it has worked every time. If they're a tiny bit dry and crumble too easily when you're shaping them, adding a tiny bit more oil helps keep everything together. Cinnamon sprinkled on top is great, and I tried adding a tiny half-teaspoon of almond extract once.
