Do you make mooncakes?

Yes, I caught my neighbor making it last night, he wanted to share it with our other neighbor, and then he changed his mind, and I 'wanted' it. Needless to say, our poor neighbor is decomposing, and we're both facing murder charges.

I suggest googling recipes, but there are date paste ones I've gotten at my favorite chinese bakery, although I've no idea about the recipe.

You could also try a filling of sweet potato, I rememeber once looking for recipes for Ube, the purple sweet potato, and finding moon cake recipes using ube.

I've made them a few times but my Chinese friends make them better than me so I try to angle an invite!  The lotus paste ones go down well with people who like peanut butter as long as you warn them that the taste is in the same family of flavours.  My observation is that when people reject "foreign food" straight off the batt it's because their expectations have been confounded so it helps to say "this more/less sweet/runny/stodgy than your food" and also warn of unexpected fish/cheese/fermented thing when the combination is unusual/unheard of in that person's food culture.

Neat that you're doing some traditional ones. The sky's the limit with your alternates! Check out the Wikipedia page, you'll see that there are as many filling and crust variations as there are cities.
