Walnut Penuche (Microwave): A Sweet Nostalgia Trip

The scent of penuche always takes me back to my grandmother’s kitchen. She wasn’t much of a baker, preferring savory dishes, but around the holidays, a batch of this fudge-like candy would magically appear. The slightly grainy texture, the deep caramel notes, and the generous scattering of walnuts – it was a comforting, familiar treat that tasted like pure love. This microwave version brings back all those warm feelings, but without the hours spent stirring over a hot stove.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 15 minutes
• Total Time: 25 minutes
• Servings: Varies, approximately 32 pieces
• Yields: 1 (8-inch) square pan
• Dietary Type: Not specified, contains dairy.

Ingredients

• 1 1/2 cups walnuts, chopped coarse
• 2/3 cup (5.33 oz or 151g) butter or margarine
• 1 cup packed light brown sugar
• 1 (14 ounce) can sweetened condensed milk, not evaporated milk
• 1 1/2 teaspoons vanilla

Equipment Needed

• 8-inch square pan
• Aluminum foil
• 9-inch microwave-safe pie plate
• 3-quart microwave-safe bowl
• Potholders
• Electric mixer

Instructions

1. Prepare your pan: Line an 8-inch square pan with foil, ensuring the foil extends over the edges of two sides to create handles. Lightly grease the foil.

2. Toast the walnuts: Spread the chopped walnuts in a 9-inch microwave-safe pie plate in an even layer.

3. Microwave the walnuts uncovered on high for 6 to 7 minutes, stirring 3 times during cooking, until they are lightly toasted. Watch them carefully to prevent burning, as microwave power can vary. The walnuts should have a fragrant, nutty aroma.

4. Melt the butter: In a 3-quart microwave-safe bowl, melt the butter or margarine. This usually takes about 30-60 seconds on high.

5. Combine ingredients: Stir in the packed light brown sugar and the sweetened condensed milk into the melted butter until well blended. Ensure there are no lumps of brown sugar.

6. Microwave the mixture: Microwave the combined ingredients uncovered on high for 7 to 9 minutes, stirring 4 times during cooking. The mixture should be a medium caramel color and the sugar should be completely dissolved. It will also thicken considerably during this process. Again, watch closely to prevent burning. If the mixture starts to boil over, stop the microwave and stir it down before continuing.

7. Incorporate the vanilla: Using potholders, carefully remove the bowl from the microwave and place it on a heatproof surface. Stir in the vanilla.

8. Beat the penuche: Using an electric mixer, beat the mixture for 3 to 4 minutes until it is smooth and shiny. This step is crucial for achieving the right texture.

9. Add the walnuts: Add the toasted walnuts to the mixture and beat on low speed for about 1 minute, just until the walnuts are evenly distributed throughout. Be careful not to overmix.

10. Assemble and cool: Spread the penuche mixture evenly into the prepared 8-inch square pan.

11. Chill: Cool the penuche completely at room temperature, then cover the pan and refrigerate for at least 2 to 3 hours, or until the penuche is firm enough to cut.

12. Cut and serve: Once firm, use the foil handles to carefully lift the candy from the pan onto a cutting board. Peel off the foil. Cut the candy into 1-inch squares.

13. Store: Store the walnut penuche tightly covered in a cool place.

Expert Tips & Tricks

• Toasting the walnuts: Don’t skip toasting the walnuts! This step intensifies their flavor and adds a pleasant crunch to the finished penuche. Keep a close eye on them in the microwave, as they can burn quickly.
• Microwave variations: Microwave power varies. Start with the minimum cooking time and increase as needed, checking frequently to avoid burning.
• Dissolving the sugar: Ensure the brown sugar is completely dissolved during the microwaving process. Undissolved sugar can result in a grainy texture.
• Electric mixer is key: Using an electric mixer after microwaving is essential for a smooth, creamy texture. Don’t try to skip this step!
• Don’t overmix after adding nuts: Mix the nuts in gently at the end to avoid crushing them and creating a muddy texture.
• If the penuche is too soft: If the penuche doesn’t firm up enough after chilling, you may have needed to microwave it for a longer time. You can try microwaving it for another minute or two, stirring frequently, and then re-chilling.
• For an easier cut: If you are having trouble cutting clean squares, try warming your knife under hot water and wiping it dry before each cut.
• Prevent sticking: Lightly grease the foil lining with cooking spray to ensure the penuche releases easily after chilling.

Serving & Storage Suggestions

Serve walnut penuche as a delightful treat with a cup of coffee or tea. It’s perfect for holiday gatherings, potlucks, or as a homemade gift. Store the penuche in an airtight container in a cool, dry place for up to a week. For longer storage, keep it refrigerated for up to two weeks. While freezing is possible, it can slightly alter the texture. If you do freeze, wrap the penuche tightly in plastic wrap and then place it in a freezer-safe container for up to a month. Thaw in the refrigerator before serving.

FAQs (Frequently Asked Questions)

Q: Can I use evaporated milk instead of sweetened condensed milk?
A: No, sweetened condensed milk is crucial for this recipe. Evaporated milk is not sweet enough and will not provide the necessary richness and texture.

Q: My penuche is grainy. What did I do wrong?
A: The graininess is likely due to the brown sugar not fully dissolving. Make sure to stir thoroughly while microwaving and ensure the sugar is completely dissolved before adding the vanilla and nuts.

Q: Can I make this without a microwave?
A: While this recipe is specifically designed for the microwave, you can adapt it to the stovetop. Melt the butter in a saucepan, then stir in the brown sugar and sweetened condensed milk. Cook over medium heat, stirring constantly, until the sugar is dissolved and the mixture is thickened and caramel-colored. Proceed with the rest of the recipe as directed.

Q: How do I prevent the penuche from sticking to the foil?
A: Lightly grease the foil with cooking spray before lining the pan. This will help the penuche release easily after chilling.

Q: How long does this penuche last?
A: Stored properly in an airtight container, the penuche will last for up to a week at room temperature or up to two weeks in the refrigerator.
