Have you ever wondered why flowers are not really included in the human diet? Do flowers look better than they taste? When did our ancestors realise that some flowers are delicious to eat while some others taste yucky? These questions popped up in my mind when I learned about dork khajon (ดอกขจร), otherwise known as milkweed flower or cowslip creeper flower. I never knew of their existence before but after seeing them displayed in Thai supermarkets and fresh markets, I became curious about this particular type of edible flower. Curious, I googled more about them and found out that cowslip creeper flower is common in Thai and Southeast Asia cooking.
