What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Cut seitan into thin, even strips to maximize surface area for browning and sauce coating.
- 2Blanch the broccoli for exactly 1 minute, then plunge into ice water to preserve its bright green color and crunch.
- 3Don't overcrowd the wok when searing seitan; cook in batches if needed for proper browning.
- 4Stir the sauce again just before adding it to the wok, as the cornstarch settles quickly.
- 5Cook the sauce just until it turns glossy and thickens—overcooking can make it gummy.
- 6For extra texture, toast the sesame seeds in a dry pan until fragrant before garnishing.

Extra VeggieExtra-Veggie
Add sliced bell peppers, snap peas, or carrots along with the broccoli for more color, texture, and nutrients. Increase sauce by 1 tablespoon soy sauce and 1 teaspoon cornstarch to coat the extra vegetables.
Spicy SichuanSpicy Sichuan
Add 1 teaspoon Sichuan peppercorns and 1 tablespoon doubanjiang (chili bean paste) to the sauce for a numbing, spicy kick. Omit red chili flakes if using doubanjiang to avoid overwhelming heat.
