- That sauce hits every perfect note sweet, savory, and deeply satisfying
02 -
- Cutting against the grain matters more than almost anything else for texture
- The sauce will look thin at first but thickens beautifully as it cooks
03 -
- Partially freeze the steak for 20 minutes to get paper thin slices easily
- Make a double batch of sauce and freeze half for next time
