Making fruit puree is straightforward: blend ripe fruit (raw or cooked) with a small amount of liquid until smooth. The whole process takes under 15 minutes for most fruits. Whether you’re making baby food, a cooking ingredient, or a topping, the technique is essentially the same, with small adjustments depending on the fruit you choose.
Which Fruits to Cook and Which to Blend Raw
Soft, ripe fruits like bananas, mangoes, avocados, peaches, and ripe pears can be pureed raw. They break down easily in a blender or even under a fork. Harder fruits like apples, firm pears, and quince need to be cooked first until they’re soft enough to pierce with a knife. Stone fruits and berries fall somewhere in between: ripe versions blend fine raw, but cooking them first gives a smoother, more uniform texture.
If you’re making puree for an infant, cooking is the safer default. Wash all fruits and remove skins, peels, pits, and seeds before cooking. Steam, boil, bake, or microwave until the fruit is soft and tender enough to mash easily with your fingers. For adults, raw purees preserve more nutrients and have a brighter, fresher flavor.
Step-by-Step Preparation
Start by washing your fruit thoroughly under running water. Peel if needed (more on that below), then remove any pits, seeds, or tough cores. Cut the fruit into roughly even chunks, about one inch, so it cooks and blends evenly.
If you’re cooking the fruit, steaming is the best method for purees. Place chunks in a steamer basket over boiling water for 5 to 10 minutes, checking tenderness with a fork. Steaming keeps the fruit out of direct contact with water, which helps preserve flavor and some nutrients. Baking works well too, especially for apples and stone fruits: spread the pieces on a lined baking sheet at 375°F (190°C) for 15 to 20 minutes. Boiling is fastest but pulls more flavor and vitamins into the water.
Transfer the cooked or raw fruit to a blender or food processor. Blend on high until smooth. If the mixture is too thick, add liquid a tablespoon at a time. Water works, but you can also use breast milk or formula for baby food, or juice and coconut water for adult recipes. For a chunkier texture, pulse instead of running the blender continuously, or mash with a fork or potato masher.
To Peel or Not to Peel
Fruit peels contain significantly more fiber and beneficial plant compounds than the flesh alone. Apple skin, for instance, has a higher concentration of dietary fiber than the pulp. Lemon peel contains roughly double the fiber of the peeled fruit. If you’re making puree for yourself and want the nutritional boost, leaving thin, edible skins on fruits like apples, pears, peaches, and plums is worth considering. A high-powered blender will break them down into a smooth consistency.
For baby food, peeling is the standard recommendation because skins can create a texture that’s difficult for young eaters to manage. For cocktail syrups, sauces, or any recipe where silky texture matters, peel first or strain the finished puree through a fine-mesh sieve.
Preventing Browning
Apples, pears, bananas, peaches, and avocados start turning brown within minutes of being cut. This is harmless but can make your puree look unappetizing. The simplest fix is speed: prep and blend quickly. If you need to hold cut fruit before blending, toss it in a solution of half a cup of bottled lemon juice mixed into two quarts of cold water and let it soak for about 10 minutes. You can also dissolve one teaspoon of pure ascorbic acid (vitamin C powder) in a gallon of cold water for the same effect. For small batches, just squeeze a little fresh lemon juice directly over the cut fruit before blending.
Fixing Texture Problems
Watery purees are common with fruits like watermelon, oranges, and cooked berries. If your puree is too thin, you have a few options. Cooking it down in a saucepan over medium-low heat for 10 to 15 minutes evaporates excess moisture and concentrates flavor. For a no-cook approach, chia seeds work surprisingly well as a natural thickener. They absorb up to 30 times their weight in water, forming a gel that thickens without altering flavor. Stir in a teaspoon or two, let the puree rest for 15 to 20 minutes, and the seeds soften into a texture similar to tiny tomato seeds. This works especially well for jam-like spreads and smoothie bases.
If your puree is too thick, thin it gradually. Add liquid one tablespoon at a time and blend again. It’s much easier to thin a puree than to thicken one.
How Cooking Affects Nutrients
Heat breaks down vitamin C, which is the nutrient most affected by cooking. Steaming retains more than boiling, but losses still vary widely depending on the food and cooking time. Studies on steamed vegetables found vitamin C retention ranged from as low as 0% (in leafy greens like chard) to nearly 90% (in zucchini). Firmer, denser produce tends to hold onto its vitamin C better than delicate, thin-walled foods. The takeaway: keep cooking times as short as possible, use steaming over boiling when you can, and blend in any cooking liquid to recapture nutrients that leached out.
Fat-soluble vitamins and minerals are much more heat-stable, so cooking has minimal impact on those. And cooking actually increases the availability of certain beneficial compounds in some fruits, particularly those with deep red and orange pigments.
Storage and Shelf Life
Freshly made fruit puree keeps in the refrigerator for 1 to 2 days when stored in an airtight container, according to FoodSafety.gov. Strained fruit purees can last 2 to 3 days refrigerated. For longer storage, freezing is the way to go. Homemade purees stay safe in the freezer for 1 to 2 months, though commercially strained versions can hold quality for 6 to 8 months.
The easiest freezing method is pouring puree into ice cube trays, freezing until solid (about 4 to 6 hours), then popping the cubes into a labeled freezer bag. Each cube holds roughly one ounce, making it simple to thaw only what you need. Silicone trays release the cubes more easily than rigid plastic ones. Thaw in the refrigerator overnight or by placing the container in a bowl of warm water for about 20 minutes. Avoid refreezing thawed puree.
Puree for Babies
The World Health Organization recommends introducing complementary foods, including fruit purees, at 6 months of age alongside continued breastfeeding. At 6 to 8 months, aim for 2 to 3 servings of complementary food per day, increasing to 3 to 4 times daily between 9 and 11 months. By 12 to 24 months, you can add 1 to 2 nutritious snacks on top of regular meals.
For first purees, single-ingredient options like sweet potato, banana, pear, or avocado let you identify any sensitivities. Start thin and smooth, almost the consistency of heavy cream, then gradually thicken the texture over weeks as your baby adjusts. Once several individual fruits are tolerated, you can start combining them. Add liquid (breast milk, formula, or water) to reach the right consistency, and always test the temperature before serving.
Quick Fruit-Specific Tips
- Apples: Peel, core, and steam for 8 to 10 minutes. Blend with a splash of water. A pinch of cinnamon pairs well for adult versions.
- Bananas: No cooking needed. Just peel and blend or mash with a fork. Use ripe bananas with brown spots for the sweetest result.
- Berries: Blend raw, then strain through a fine-mesh sieve to remove seeds. For strawberries, hull before blending.
- Mangoes: Peel, remove the pit, and blend raw. Frozen mango chunks work just as well and are often cheaper.
- Peaches: Blanch in boiling water for 30 seconds, then transfer to ice water. The skins slip right off. Blend raw if ripe, or steam for 5 minutes if firm.
- Pears: Ripe pears blend raw. Firm pears need 6 to 8 minutes of steaming. Bartlett and Anjou varieties have the smoothest texture.
