Kelp Recipes

In 2020, GreenWave received a USDA Farmers Market Promotion Program (FMPP) grant to help improve market opportunities for kelp farmers. As part of this grant, we worked with Farm Fresh Rhode Island’s Harvest Kitchen, a small-scale co-packing facility, to develop and manufacture four shelf-stable, value-added food products that profile fresh sugar kelp as a primary ingredient.

These recipes, along with the scheduled processes to mass-produce them, were validated by Cornell University’s Food Venture Center, and are now open-source and available to all farmers. Any farmer or co-packer across the country could replicate these recipes to create their own, branded shelf-stable kelp products. To learn more about working with co-packers, or read about the project with Harvest Kitchen, click here.

Important Note

Home pickling and canning must be done with care to ensure safety, with special attention given to disinfecting and temperature control. Introductory information on canning can be found here, and a home picking guide here. If you are not an expert in pickling, you can always opt for quick pickling and omit the canning stage. Quick-pickled kelp pickles will keep in your refrigerator for up to three weeks. If you suspect your food is spoiled, discard it. 

If you don’t have access to fresh kelp, you can source sustainably grown Maine kelp from our friends at Atlantic Sea Farms. This will lead to a slightly softer texture in the pickles which would be great for the Kelp Salsa Verde and Kelp Dijon Mustard.
