I use it in Thai cooking and for San Bei Chicken. We don’t use Thai basil as often in Singapore.
If you have a yard, this is one of the best plants to grow in early spring. Buy a sapling or two and keep trimming it at the tips, or when the flowers appear and you will have Thai basil all summer.
I have four types of basil, Thai basil, purple Thai basil, Italian basil and purple basil. With my plot of herbs I can use these ingredients at a whim, without having to run to the store and spend two bucks on more herbs than I can use. I grew a few herbs in a pot for my daughter, Alison, and she hasn’t killed them yet.
And while you are at it, you might as well also grow Vietnamese mint, which is great in instant noodles. And thyme, and mint, and parsley because these are great fresh and too expensive to buy at the supermarket.
