Yes, you can make paste from roasted nuts. Roasting enhances the flavor and can make the nuts easier to grind into a smooth paste.
Making nut paste, like almond butter or cashew butter, typically involves grinding nuts until they release their natural oils and form a smooth consistency. While soaking nuts is sometimes done to soften them or reduce phytic acid, roasting serves a different purpose and can be beneficial for paste-making.
Here's a breakdown of why roasting works well:
Flavor Enhancement: Roasting nuts brings out their natural flavors, resulting in a more flavorful paste. The Maillard reaction, a chemical reaction between amino acids and reducing sugars, occurs during roasting, creating complex and desirable flavors.
Easier Grinding: Roasting can slightly dry out the nuts, making them more brittle and easier to grind into a fine powder. This can speed up the paste-making process and result in a smoother texture.
Oil Release: The heat from roasting can help to release the oils within the nuts, which is crucial for achieving a smooth, spreadable paste. The warmth encourages the oils to flow more freely.
To make nut paste from roasted nuts:
Roast the Nuts: If you haven't already, roast the nuts at a moderate temperature (around 350°F or 175°C) for 10-15 minutes, or until they are fragrant and lightly golden. Let them cool slightly.
Grind the Nuts: Place the roasted nuts in a food processor or high-powered blender. Process continuously, scraping down the sides as needed. Initially, the nuts will turn into a coarse powder.
Continue Processing: Keep processing until the nuts release their oils and form a smooth paste. This may take several minutes, depending on the power of your appliance and the type of nut.
Add Salt (Optional): Add a pinch of salt to enhance the flavor. You can also add other flavorings like honey, cinnamon, or vanilla extract.
Be patient during the grinding process. It can take several minutes for the nuts to release their oils and form a paste. Avoid overheating your food processor by taking breaks if necessary.
