March is National Peanut Month in the US, a crunchy, creamy celebration of this versatile legume. Home cooks lean into peanut butter cookies, brittle, and pies while also stirring peanuts into savory favorites like satay, pad thai, and kung pao. Roast raw peanuts to heighten aroma, blitz warm nuts into fresh peanut butter, or whisk a quick peanut sauce with lime, soy, and chili. Use peanut oil for high-heat frying and keep nuts sealed and cool to prevent rancidity. Natural peanut butter benefits from a stir and can be refrigerated to slow separation.
