I also made a lemon sauce to go with them. It...sucked! I followed a recipe that I found to a T, and it tasted terrible. It had more of a vegetable stock flavor than a lemony flavor. Honestly, it tasted like extremely sweet vegetables. Yuck! I told myself that I should make it from my head but decided to follow a recipe instead. I know now that the next time I need to make a sauce, I need to go with my own thoughts. The food usually tastes better.
The spring rolls were really easy to make. I took various vegetables and combined them in a pan. I cooked them until they were very transulcent. This also meant that all of the veges kind of meshed into one. I figured out a long time ago that when you make spring/egg rolls that you want everything to have distinct flavors but also taste like one giant flavor. I wrapped them using filo dough. They made 12 spring rolls. I put them in the oven and baked them for 20 minutes.
If you want the recipe then let me know.
