Fish stock
Fish stock tends to be among the highest-histamine stocks — fish spoils quickly, and histamine formed before and during preparation carries through into the finished stock.
Fish already has a head start on histamine before it even enters the pot, making fish stock particularly high-load.
-
Fish accumulates histamine rapidly — even with refrigeration, fish proteins break down and generate histamine faster than meat, so by the time fish goes into a stock, histamine levels may already be elevated
-
Heat preserves what's already there — simmering does not destroy histamine that has already formed; whatever accumulated during handling and preparation remains in the stock, and cooling and storage afterwards can allow further buildup
If you want a light seafood flavor in a dish, a quick poach of very fresh fish in water is likely a much lower-histamine approach than a simmered fish stock.
