- Store chocolate in a cool, dry place, but never store it in the refrigerator or freezer. - Work in the ideal room conditions. Room temperature should be 68-72°F and room humidity should not exceed 50%. Use an air conditioner to regulate conditions if needed. - Ensure your chocolate doesn't come into contact with any water, condensation, or high humidity. - Make sure your chocolate is new and fresh, as older chocolate will have more tendency to bloom.
