Quince can be used to make jams, jellies, and preserves, as well as being added to fruit salads or used in baking. It can also be poached, roasted, or stewed to soften its texture and bring out its sweet, floral flavor. Additionally, quince can be used to make a delicious paste, known as membrillo, which is often paired with cheese. **

If your quince liqueur gels, you can try to gently warm it up by placing the bottle in a bowl of warm water or using a microwave on a low setting. Stir the liqueur gently as it warms to help break up the gel-like consistency. If this doesn't work, you can strain the liqueur through a fine mesh sieve or cheesecloth to remove any solidified particles. Remember to store the liqueur properly in a cool, dark place to prevent it from gelling in the future. **

Quinces are ripe when they turn from green to yellow and have a strong, sweet fragrance. The fruit should also give slightly when gently pressed.
