Flower sprouts are a unique hybrid vegetable, a cross between Brussels sprouts and kale, also known by the brand name Kalettes. They combine desirable traits from both parent plants. These small florets typically have frilly, open heads, often displaying a vibrant mix of green and purple hues. They offer a milder, sweeter taste than traditional Brussels sprouts, accompanied by a nutty flavor profile, making them a versatile addition to many dishes.
Growing Flower Sprouts
Cultivating flower sprouts at home can provide a rewarding harvest. Like their brassica relatives, they thrive under specific conditions.
Planting and Care
Flower sprouts grow best in full sun, requiring at least six hours of direct sunlight daily. The soil should be well-drained and fertile, ideally with a pH between 6.5 and 7.5. Planting typically occurs in late spring to early summer, around June or July, from seedlings about 15 cm tall, to allow for a fall or winter harvest. Seeds can be sown indoors in February or March, or directly outdoors under cover in April.
When transplanting, space plants approximately 45-90 cm apart to ensure adequate room for growth. Consistent watering is important, especially during dry periods, to maintain steady growth. These plants benefit from regular feeding with a balanced fertilizer, though too much nitrogen can promote excessive leaf growth. Supporting taller plants with stakes can prevent wind damage as they mature. Flower sprouts are cool-season vegetables, and their flavor often improves after a few light frosts.
Harvesting
Flower sprouts mature gradually, allowing for a prolonged harvest period. The small florets are ready for picking when they are firm and have reached a desirable size, typically between 2.5 to 7.5 cm in diameter. Harvesting usually begins from the bottom of the stalk, as these sprouts mature first. You can twist or snap off the individual sprouts from the main stem, or use a knife to cut them at their base. Harvesting can continue progressively up the stalk as more sprouts develop. Plants can continue to produce well into the colder months, sometimes even into the snow season.
Preparing and Cooking Flower Sprouts
Flower sprouts are a versatile vegetable in the kitchen, offering a milder and sweeter alternative to Brussels sprouts. Their unique texture and flavor make them suitable for various cooking methods.
Basic Preparation
Before cooking, properly prepare flower sprouts by washing them thoroughly under cold water to remove any dirt or debris. After washing, pat them dry with a clean towel to ensure they cook evenly, especially for roasting or sautéing. Inspect and trim tough or discolored stem ends. Smaller sprouts can be cooked whole, while larger ones may benefit from being halved for uniform cooking.
Cooking Methods and Ideas
Roasting is a popular method that brings out the nutty flavor and creates a pleasant crispness. Toss cleaned, dried sprouts with olive oil, salt, and black pepper. Spread them in a single layer on a baking sheet, ensuring not to overcrowd the pan, which allows for better caramelization. Roast in a preheated oven at temperatures ranging from 175°C to 230°C (350°F to 450°F) for about 12-15 minutes, or until the outer leaves are slightly browned and crispy, and the insides are tender.
Sautéing or pan-frying offers a quick cooking option. Heat a small amount of oil in a pan over medium-high heat, then add the sprouts. Cook for a few minutes until they begin to soften and develop some color. A splash of water can be added to the pan and covered to steam them briefly before removing the lid to allow for browning.
Steaming is another gentle method that preserves their bright green color and tender texture, typically taking about 3-4 minutes. Blanching, a brief dip in boiling water followed by an ice bath, can also be used, particularly if the sprouts will be added to salads or stir-fries later. Simple seasonings like minced garlic, a drizzle of balsamic glaze, or a squeeze of lemon juice can enhance their flavor. For added texture and richness, roasted flower sprouts pair well with ingredients such as toasted pine nuts, crumbled bacon, or grated Parmesan cheese.
Nutritional Benefits
Flower sprouts provide a range of beneficial nutrients, contributing to a balanced diet. They are a source of vitamins, including Vitamin C and Vitamin K. Flower sprouts also contain Vitamin A. Additionally, they contribute dietary fiber, which supports digestive processes. These vegetables offer antioxidants, compounds that help protect the body. With their nutrient profile, flower sprouts can be a healthful addition to meals.
