1)read the recipe and spend a couple of min visualizing the steps, what you’ll need and writing out the timing and grouping chores.
2) do some mise en place[a] (buy $50 of small duralex glass bowls for this, they’re great). E.g. do all your dry good measuring, then wet measuring, vegetable chopping in groups.
3. Set up efficiently (mise en place above), watching someone go to the cupboard 15 times and then the fridge 8 times for things in their recipe is a huge waste. Use a trash bowl so you’re not running to the sink or garbage all the time.
4. Learn knife skills (a lot of cooking schools offer a stand alone class). The right way and the wrong way to dice an onion or Julianne a pepper are like 80%+ reductions in time spent on a task…
5. Clean while you cook.
You’ll be shocked at the time savings if you combine these elements.
