- Prepare the Cucumber Topping:

I always keep a jar of Chinese sesame paste in my pantry for dishes like this. The first time I made it my roommate thought I had picked it up from a takeout spot and I knew I was onto something.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to three days. The sauce thickens as it sits so stir in a splash of water before serving to refresh the texture.
Ingredient Substitutions
If Chinese sesame paste is not available use tahini instead. It will yield a slightly lighter flavor. For extra protein stir in baked tofu or cooked edamame.
Serving Suggestions
Serve as a light lunch or pair with chilled edamame or dumplings for a more substantial meal. It also makes a great picnic item as it travels well and is enjoyed cold.

Cultural Context
Chinese sesame paste is made from roasted sesame seeds and commonly used in noodle dishes throughout Chinese cuisine. Its deep rich taste distinguishes it from Middle Eastern tahini which is milder and made with raw sesame.
