http://www.think2020.com.nyud.net:8080/jv/recipe.htm?coral-no-redirect This link has been a little swamped lately, so this is a cached version, but it is one tech-guy's explanation of his 6 year fascination with a particular type of pizza.
Complete with recipe/ingredient/explanation/picture goodness.
For any NT's who wonder what a "special interest" might look like, this could be helpful.
I don't know if this guy is an Aspie, but he probably wouldn't be denied entrance to the Aspie picnic.
Also it looks like darned tasty pizza.
