Hi DS13 had multiple food allergies but is down to just peanut and egg at the moment. He is on the egg ladder and can eat a boiled egg. He had a couple of accidental exposures to less processed egg that resulted in hives, him going very pale and sick stomach.
Lat week I made chocolate tarts - the pastry had an egg in it and was blind baked and the baked again so that was fine.
The chocolate mix was cooking chocolate, milk, cream and 1 egg yolk. The yolk was mixed in with the hot (almost boiling) milk/cream which would cook it a bit and then was poured into the pastry tarts and cooked for about 10 mins.
DS ate about 1/2 teaspoon of the tart (half pastry and half chocolate) but didnt want anymore. Within mins he told me he was having an allergic reaction. He said his tongue was tingling, he was very pale, sick stomach but also complained of feeling like he had two lumps either side of his throat. He also complained of a pain high in his chest - like at his breastbone.
He took anti histamine and the reaction stopped in about 5/6 mins. I was terrified as he never had that feeling of lumps in his throat before. His breathing was fine and he was calm.
I dont know what caused the reaction, I think the egg in the pastry and chocolate mix was cooked enough not to cause a reaction. The cooking chocolate I used was the end of a packet which he had already eaten from with no previous reaction and about 8 squares from a new packet. The new packet was Tesco own brand, no nut warning and he has eaten that brand before (but this was a new packet uneaten).
I am thinking of buying the peanut testing stripes to test the chocolate for peanut. They are about £150 for 10 -never used them before and dont know if they are any good.
I really dont know what he reacted to, it was his worst reaction and I am sh*t scared for him now that he will have an anaphylactic reaction.
