This is so easy to make. Fry tons of garlic (to lessen the guilt from eating aligue or crab fat, maybe) in butter (yes, not olive oil or corn oil) and when the garlic begins to smell (garlicky!), add some shrimps (optional) then the aligue. Cook for a minute or two before adding your rice. Then garnish with strips of fresh basil (optional).
Going to Bangkok is not complete if you haven't tried their famous Thai Milk Tea which are sold on the streets for 20 baht. It's not really hard to find a milk tea seller because there always seem to be one nearby.
