Jalapenos can make any dish interesting. From pizza to burgers and everything in between. Add some spice to your dishes. With a Scoville rating between 30,000 and 100,000, you can be assured no dish will be boring. A mature jalapeño chile is 5–10 cm long and hangs down with a round, firm, smooth flesh of 25–38 mm wide. It can have a range of pungency, with Scoville heat units of 3,500 to 8,000. It takes 80 days for them to mature from seed to harvest, and the plants grow about 2 feet tall.
