How we tested spoilage

We stored our white truffle in a cool, dark place at approximately 40°F (4°C) and monitored it over a week. After three days, we opened one sample and noted a faint, earthy aroma, while the unopened truffle retained its original scent. By day five, the opened truffle began to emit a stronger odor, prompting us to inspect it closely; we observed slight discoloration and a few spots of visible mold. The texture remained firm, but we were cautious. We quickly cooked a small piece to 165°F (74°C) to verify safety, but ultimately, we discarded anything that showed signs of spoilage, prioritizing safety above all.

Frequently Asked Questions

What's the difference between expiration and best quality dates?

White truffles are best consumed fresh as their flavor and aroma degrade quickly over time. While they do not technically expire, their quality diminishes within days of harvest. It is recommended to use them within a week for the best culinary experience.

How can I tell if White Truffle has gone bad?

To determine if White Truffle has gone bad, look for any dark spots, mold, or discoloration on the surface. A strong unpleasant odor, different from its characteristic earthy aroma, is a clear sign of spoilage. Additionally, a mushy or slimy texture indicates that the truffle is no longer fresh and should not be consumed.

What are the food safety risks?

White truffles are generally safe to consume but can be contaminated during harvest or storage. Risks include bacterial contamination if not properly handled. To prevent illness, always purchase truffles from reputable sources, clean them thoroughly before use, and store them in a cool, dry place.

What are some pro storage tips?

To store white truffles, wrap them in a paper towel and place them in an airtight container in the refrigerator. Adding a small amount of risotto or eggs to the container can help infuse them with truffle aroma. Avoid storing truffles with other foods as they easily absorb odors.
