1) If you love heat, try using a different chili pepper to season your broth with. The cayenne isn't to spicy and just gives this broth a subtle kick. You can up the heat of the cayenne pepper used in the broth by letting it soak in the broth longer. Hubbs and I noticed this when we went back for seconds. The broth had been sitting for an additional 15 -20 minutes and was far spicier.2)Feel free to use different colored bell peppers or to use those on hand. I don't recommend green bell pepper for this soup.3)You can also use rice noodles in place of the cellophane noodles.4)This is gluten free if you make sure to use gluten-free broth.
