Great question! I had to do a little research for this one, because I've never actually used canned coconut milk before. However, I now feel inspired to try some of these out myself!
If you are in the mood for a little dessert, try this Coconut Milk Bread Pudding (http://www.thekitchn.com/recipe-coconut-bread-pudding-137917). You'll need butter, bread, pistachios, candied ginger, coconut milk, eggs, granulated sugar, cardamom and salt.
You can also keep things simple, and just make some whipped cream (http://www.thekitchn.com/how-to-make-whipped-cream-from-152490).
Or, if you are looking for a dinner idea, why not try this Chicken in Coconut Milk? (http://www.thekitchn.com/recipe-chicken-in-coconut-milk-with-lemongrass-recipes-from-the-kitchn-81026) You'll need a whole roasting chicken, as well as a Dutch oven (or a heavy pot where the chicken can fit securely).
