For silicon molds, just spoon the herb paste into your molds and smooth flat. I place a layer of plastic wrap over it until frozen just to keep my freezer clean. The silicon mold is flexible, so I take the filled molds and set it on a cutting board or tray and put the whole tray into my chest freezer until frozen and then pop them out and store in a freezer bag. This is super quick & easy to make, and a great way to quickly reduce any surge in herbs. Herbs not only make everything taste fantastic, but they also retain their nutritional value when frozen, so you can enjoy all of their benefits well into winter!
I love growing a lot of herbs, and I love preserving them too. Since our growing season in Wisconsin is fairly short, finding many different ways to preserve things so we feel like we have a wonderful variety the rest of the year is key.
Looking for other ways to preserve your herbs? Try my veggie bouillon recipe - I love making a lot of this in the summer to use all winter long. SUCH an amazing flavor!
