For a smoother jelly, strain the blackberry juice through a cheesecloth-lined sieve before using. Adjust the amount of jalapeño to your personal preference. For a milder jelly, remove the seeds and membranes from the jalapeños before mincing. For a spicier jelly, leave some of the seeds intact. Sterilize your canning jars by boiling them in water for 10 minutes before filling them with jelly. Be sure to use a heavy-bottomed saucepan to prevent the jelly from scorching. If you don't have fresh blackberries, you can use frozen blackberries, thawed and strained.
