Red and yellow capsicums, also known as bell peppers, are two common varieties of the Capsicum annuum species. They are similar in taste and texture but differ in color, with red capsicums being fully ripe and yellow capsicums being slightly less mature. Both red and yellow capsicums are sweet and crisp, making them popular additions to salads, stir-fries, and other dishes. They are also rich in vitamins and antioxidants, making them a healthy choice for your diet.
