Yes! Lime leaves: Fresh lime leaves last about 2 weeks in the fridge, or can be frozen. Wash first, then dry very well so they don’t stick together. Then freeze. Prevent freezer burn by wrapping in foil first, then in a ziploc and remove all the air out.  Lemongrass: Trim off the bottoms and woody tops and peel away tough outer layers. Cut into 2 to 4-inch pieces. Transfer to a freezer-safe bag and freeze for a few months. To extend the shelf life, wrap lemongrass in foil first, then place in the bag.   Galangal: Slice thinly, then spread out on a plastic wrap-lined sheet pan or plate in a single layer to prevent sticking. Freeze, and once frozen, transfer to a freezer-safe bag and freeze.  Thai chile peppers: Freeze whole in a freezer-safe bag or container.
