Some time ago, a friend pointed me to this magical stuff that turns fats into powders. T’other day, I finally got my hands on some of this tapioca maltodextrin, as it’s called; it’s a starch, and there’s really not much more to turning a really fatty thing into a powder than mixing the two things together.
The starch is close enough to flavourless, but any statements you may have encountered to the effect that you put the powdered (olive oil/peanut butter/hazelnut-and-chocolate-spread) into your mouth and voilà! it’s the original stuff again! are not really operative. There’s a noticeable effect on the texture, and you’ve got a bunch of starch that wasn’t there before.
Still, it’s amazing to work with and it’s truly a surprise for your taste buds.
