A common way to prepare Thai curry is haw mok. Traditionally steamed in banana leaf cups, which imparts a special aroma, nowadays Thai restaurants often times take a short-cut by using aluminum foil, which unfortunately gives a metallic taste. It is also possible to steam the fish puree in small cups or as pictured, in small clay pots (be sure to also see our suggestions for banana leaf replacements). If you visit Thailand look for this delicious creamy blend of fish, curry paste and coconut milk in the open markets.
