A1 Steaksauce is a condiment produced by the Kraft Brand (please see this link for more Kraft Brand information). The steak sauce, despite being called steak sauce, is vegan. The ingredients for the original recipe are shown below.
TOMATO PUREE (WATER, TOMATO PASTE), DISTILLED VINEGAR, CORN SYRUP, SALT, RAISIN PASTE, CRUSHED ORANGE PUREE, SPICES AND HERBS, DRIED GARLIC AND ONION, CARAMEL COLOR, POTASSIUM SORBATE (TO PRESERVE FRESHNESS), XANTHAN GUM.
Further, upon reviewing the ingredients for the rest of the brand, they all appear vegan friendly. No mention of the typical non-vegan ingredients for condiments (honey, anchovies, …).
