If your mix is 6+ months after that is date, usage one-fourth of the amount. If it’s an ext than a year, usage half. 2 years or more? usage three-fourths or also the whole amount (if it’s “expired” for prefer three years).

Instead, use it in a recipe you wanted to check out throughout the weekend, therefore if things go south, it’s not a big deal.
