Scotch bonnet peppers, bananas and tomatoes at the Ocho Rios farmers’ market. One of the hottest chile peppers, Scotch bonnets come in vivid shades of red, orange and green and are used throughout the Caribbean. Though they look similar to habaneros, Scotch bonnets have a citrus note that makes them undeniably different. You can control the heat of a dish a little by discarding the membranes that hold the seeds, which are the spiciest part of chile peppers, along with the seeds themselves. Be sure to wash your hands thoroughly after handling hot peppers or wear rubber gloves. If you can’t find Scotch bonnet peppers, habaneros can be substituted.
