America's Test Kitchen - Which Frozen Ingredients You Should Cook With? | Techniquely with Lan Lam
Frozen produce is advantageous for cooking as it reduces prep time and provides access to seasonal or non-local ingredients. The freezing process damages cell walls, releasing juices and softening textures, which can be beneficial in certain recipes. For example, using frozen spinach in gnudi eliminates the need for blanching and chopping, while frozen cranberries in relish offer a tender texture without cooking. Quick freezing methods like IQF help retain texture and juice. Frozen produce is ideal for cooked dishes, as cooking naturally softens food, masking any texture changes from freezing. Examples include pasta piselli with frozen peas and raspberry iced tea using frozen berries for enhanced flavor. Frozen foods also reduce food waste and allow for year-round recipe versatility.

3. 🥬 Best Uses for Frozen Produce
- Frozen produce is ideal for cooked dishes as cooking naturally softens food, masking any texture changes from freezing.
- For instance, frozen spinach is excellent in soups, stews, and casseroles where its texture is less critical.
- Frozen berries are perfect for smoothies, baking, or making sauces, where the focus is on flavor rather than texture.
- Maximize the benefits of frozen vegetables by sautéing or roasting them directly from frozen to enhance flavor and preserve nutrients.
- Incorporate frozen corn in chowders and salsas where it contributes sweetness and color without affecting texture.
4. 🧀 Making Spinach Ricotta Dumplings (Gnudi)
- Gnudi are made by binding ricotta and spinach with egg and flour, then poached and served with a sauce.
- To ensure Gnudi are airy and light, use minimal binder and remove as much water as possible from cheese and spinach.
- Traditionally, spinach must be washed, trimmed, blanched, shocked, squeezed dry, and chopped before making dumplings.
- Alternatively, use frozen spinach, defrost it, and squeeze out excess water to skip some preparation steps.
- The desired texture is tender, with ricotta being light and airy, and just enough binder to hold everything together.
- For cooking, poach the formed dumplings in simmering water until they float, indicating they are cooked through.
- Serve with a simple butter and sage sauce for a classic pairing or a tomato-based sauce for more flavor variety.
- Ensure precise poaching time by observing when dumplings float, usually around 4-5 minutes, to prevent overcooking.
- To enhance flavor, consider adding nutmeg or Parmesan to the dumpling mixture.
5. 🍝 Expanding Recipe Options with Frozen Foods
- Frozen foods simplify cooking and reduce preparation time.
- Using frozen peas allows for the preparation of pasta piselli year-round, not just in spring.
- Pasta piselli is a quick dish, ready in about 30 minutes without defrosting peas.
- Frozen produce options include edamame, baby lima beans, pearl onions, artichoke hearts, pineapple, peaches, and cherries, which can be used in various cooked applications.
- Frozen fruits and vegetables can be chopped or pureed effectively.
- Frozen options can sometimes be preferable to fresh, even without cooking.
6. 🍊 Cranberry Relish and Beyond
- Utilizing frozen cranberries instead of fresh ones results in a more tender texture for cranberry relish, effectively addressing the issue of raw cranberries being too chewy.
- Swapping orange for clementine in the recipe enhances the citrus flavor, adding more character to the dish.
- The relish maintains its fresh aroma and flavor because it is not cooked, preserving its natural essence.
- Cranberry relish pairs well with a variety of dishes such as roasted butternut squash, grilled pork, or as a condiment with blue cheese on crackers, showcasing its versatility.
- The use of a food processor bruises the cranberries, making them tender, while freezing prevents them from being crunchy.
- Preparation tip: blend cranberries and citrus fruits using short pulses in a food processor to achieve the desired consistency without over-processing.
7. 🫖 Enhancing Iced Tea with Frozen Berries
- Utilize frozen berries to enhance flavor, as their damaged cells release more juice compared to fresh berries.
- For a vibrant flavor profile, mash raspberries with basil, sugar, and lemon juice.
- Prepare by steeping tea separately for four minutes, then combine with the berry mixture and ice water, allowing it to steep for an hour.
- This approach not only customizes sweetness and flavor intensity but also eliminates the need for store-bought flavored teas.
- Frozen berries provide a practical advantage by being available year-round, ensuring consistent flavor enhancement.
