Boniato Blanco: A Sweet & Nutritious Tropical Tuber

An Introduction to Boniato Blanco

Boniato blanco, also known as white sweet potato, is a versatile root vegetable packed with nutrients and natural sweetness. This creamy-fleshed tuber is a popular ingredient in Latin American and Caribbean cuisines, where it is used in both savory and sweet dishes. When planning an ecological garden or looking for ingredients to use in ancestral recipes, boniato blanco can be a delightful addition.

What is Boniato Blanco?

Boniato blanco is a cultivar or variety of sweet potato, belonging to the species Ipomoea batatas. Unlike the more familiar orange-fleshed sweet potato, boniato blanco has a pale cream or white flesh when raw. The skin color can range from cream to light brown or reddish purple. When cooked, the flesh becomes soft and turns a translucent whitish hue while still retaining a moderately sweet taste and starchy yet fluffy texture.

This boniato variety likely originated in South America before spreading to tropical regions around the world. It remains an integral part of traditional cuisines across Latin America and the Caribbean islands. In Puerto Rico, Cuba, the Dominican Republic, and other countries, boniato blanco is fashioned into classic desserts like dulce de boniato but also used as a starchy staple much like white potatoes.

Growing Conditions for Boniato Blanco

Like all sweet potato cultivars, boniato blanco requires a long, warm growing season to produce substantial yields. These heat-loving vines need 4-5 months of temperatures around 70-85°F (21-29°C). They are not frost-tolerant whatsoever.

Ideally, boniatos should be grown in loose, well-draining, sandy loam soil. Avoid heavy clay soils or any locations prone to waterlogging. Amend the planting bed with plenty of organic compost to encourage vigorous vine growth and large storage roots. The soil pH should be slightly acidic, around 5.5-6.5.

Sweet potatoes can be grown from transplants (“slips”) or from mature tubers saved from a previous harvest. For a faster start, use transplants to establish vines early in the season. Water boniato vines regularly to keep the soil moist but not saturated.

Harvesting and Storing Boniato Blanco

Boniato blanco typically matures in about 4 months when grown from slips. Tubers can be dug up carefully by hand anytime the storage roots seem plump. Avoid damaging the delicate skins. Cure freshly dug tubers in a dark, ventilated area for 1-2 weeks to toughen skins for storage.

When properly cured, boniato blanco will keep for 2 months or longer if stored around 55°F (13°C) with high humidity. Do not refrigerate. Check periodically for sprouts or mold growth. Displaying a basket of boniatos makes for a unique presentation while the tubers last!

Enjoying Boniato Blanco

Cooking preparations

This creamy sweet potato needs little preparation before cooking. Gently scrub off soil, then peel off the thin outer skin with a vegetable peeler or paring knife. Rinse or soak briefly. Slice washed boniato into cubes, discs, strips, or mash for simplified cooking.

Raw boniato flesh quickly begins to oxidize and turn brown after cutting. To prevent discoloration, place prepped pieces immediately into acidulated water (water with lemon juice/vinegar) until ready to cook.

Boniato Blanco Cooking Methods

Being highly versatile, boniato blanco can be boiled, baked, fried, mashed, pureed into soup, or integrated into both sweet and savory recipes that use potatoes, yams, or carrots. The cooking time ranges 15-45 minutes depending on the preparation method and whether pieces have been peeled.

This hearty tuber retains its shape relatively well when boiled, making it ideal for stews, curries, soups/sancochos, and sides to accompany meat dishes. Cubes of boniato lend themselves particularly well to being roasted along with other root vegetables.

For a simple side, boil or bake boniato pieces until tender, then mash with butter, warm milk, salt, and pepper for a sweet, smooth puree. Fried boniato fries also prove irresistible!

Using Boniato Blanco in Desserts

Boniato blanco makes for a perfect base to sweet, comforting desserts thanks to its unbeatable natural sweetness. When cooked until soft and blended smooth, it creates a subtly sweet flavor and creamy, pudding-like texture.

Classic Latin desserts spotlighting this humble tuber include:

• Dulce de boniato - Sweet boniato paste
• Boniato pie (tarta de boniato)
• Candied boniato (boniato en almíbar)
• Boniato custards like flan

For a simple yet delicious homemade dulce de boniato, boil peeled, cubed boniatos until falling apart tender. Drain then mash thoroughly with butter, milk, vanilla, cinnamon, and just enough brown sugar to balance the sweet potato's natural sugars. Cook, stirring frequently, until thickened to a dense paste. Spoon into jars to enjoy for weeks!

The Benefits of Adding Boniato Blanco

Beyond being naturally sweet and tasty, incorporating boniato blanco into your cultivated garden or regular recipes offers loads of benefits.

Excellent Nutrition

This often overlooked tuber overflows with key vitamins and minerals. Boniato blanco provides antioxidants like vitamins C and E along with lots of fiber, potassium, vitamin B6, niacin, magnesium, and more. Its nutrition resembles a white potato but with higher antioxidant levels.

Adaptable and Multipurpose

Unlike starchy cassava, vibrant orange yams, or watery true white potatoes, the boniato blanco fills a unique role with its moderately sweet flavor profile and fluffy yet substantial texture when cooked. It can lend its versatility to both main courses and desserts.

Easy to Grow

Compared to some finicky vegetables, boniatos are joyfully simple to grow in any hot, long summer environment. They require little upkeep beyond ample warmth, water, soil nutrients, and proper harvesting/curing methods. Growing your own boniato blanco guarantees access to their sweetness!

With proper TLC given to both vines and developing tubers, a small boniato patch can supply fresh ingredients for numerous ancestral dishes to feed a family for months on end.
