Thai: บวบเหลี่ยม (buap liam)
This vegetable has deep ridges and dark green skin. To prepare the vegetable, you cut the outer ridges and skin off, and cut the vegetable at an angle, twisting the vegetable 1/4 turn after each cut. You’re left with odd shaped pieces which, for some reason, are better. If you can’t find angle loofa, you can probably substitute with cucumber, as they both have a very mild flavor.
Storage: Store in a plastic bag in the refrigerator. This will keep awhile if kept cool.
