Chef Hacks & Prep Tricks
💡 Towel Wringing Trick: For crispy fritters or moist bread that does not turn gummy, toss grated zucchini with 1 tsp salt, wait 10 minutes, then wring out hard in a clean tea towel to extract 1/2 cup of water!
💡 High-Heat Pan Sear: Cook thick half-moons in a ripping hot dry cast iron skillet with oil added at the very end; this prevents steaming and gives gorgeous caramelized brown crusts.
