I make fudge every year, normally orange creme. This year, I tested out a raspberry and creme fudge within 24 hours. About 2 hours after making it, I had small but multiple hives appear all over my arms, torso, neck, and backside. Today, not even 12 hours later, they are huge swollen lumps and I am shivering; cortizone cream is not helping much. Is this potentially an allergic reaction to raspberry extract?
