FAQs

How can I thicken my stir fry sauce?

To thicken the sauce, ensure it's cooked over medium-high heat for a few minutes after adding it to your stir fry. The cornstarch will activate and thicken the sauce as it heats.

Can I make this sauce ahead of time?

Yes, you can prepare the sauce in advance and store it in the refrigerator for up to a week. Shake well before using.

Is this sauce gluten-free?

To make the sauce gluten-free, use tamari instead of regular soy sauce.

Can I use a different oil instead of sesame oil?

While toasted sesame oil provides a distinct flavor, you can substitute it with other oils like olive or vegetable oil, keeping in mind the flavor profile will change.

What vegetables work best with this sauce?

Common choices include mushrooms, carrots, sugar snap peas, broccoli, onions, bell peppers, green onions, water chestnuts, and baby corn.

Can I add protein to my stir fry with this sauce?

Absolutely. This sauce complements various proteins such as chicken, beef, tofu, chickpeas, and tempeh.

How long does it take for the sauce to thicken?

Once added to the stir fry, the sauce typically thickens within 3–5 minutes of cooking over medium-high heat.

Can I freeze the sauce for later use?

Freezing is not recommended as the cornstarch may separate upon thawing, affecting the sauce's consistency.

Is this sauce suitable for a vegan diet?

Yes, all the ingredients are plant-based, making it suitable for vegans.

How much sauce should I use per serving?

Start with a few tablespoons per serving and adjust according to taste and the quantity of your stir fry.
