Yes, Malaysian's basil is the Daun Selasih. Used for M'sian food. But for the pesto, is Sweet Basil. Usually can find at the fresh herb sections at Jusco, Cold Storage, Isetan and so on.

Still, there were ready made pesto for sale at some supermarkets. Great for pasta if you lazy to cook. Just cook the pasta and toss around with spaghetti along with Parmesan cheese. If you have ripe avocados, add in. Yumm
