Unusual: None of these are considered even moderately allergenic foods and thus I am puzzled by the reactions. The absence of itching also speaks against an allergic reaction . Do you have the same reaction whether these are eaten raw or cooked? If these were consumed in the form of hot soup, the reaction may just be one pointing to the presence of rosacea which causes flushing.
