Tried the Heston fries (per his cooking show on YouTube ) today. Did per video's instructions, adding freezing step between steps 2 & 3 (per his book, I hear). Very good - Thinking this one through, the freezing seems key - between steps 1/2 and 2/3 - not for direct drying, but for indirect, as a frozen baton of potato will take more time in the oil to get to the cusp of browning in step 2, and browning, in step 3, if frozen. This gives the water on the outer portion of the baton more time to boil (or sublimate, in the beginnning of 3) away before being "done". Either way, yummy. It also explains at least part of why frozen pre-cooked store bought fries are quite yummy.
