Malt vinegar is a type of vinegar that is made by malting barley, brewing it into ale, and then turning the ale into vinegar. It has a nutty, toasted flavor from the malted barley and bacterial processes that happen during the fermentation stage, making the final product sweeter and milder than other kinds of vinegar. Here are some common uses of malt vinegar:

• Fish and chips: Malt vinegar is a classic accompaniment to cut through the oiliness of fried fish and potatoes.

• Marinades and chutneys: Malt vinegar can be used in sweet-sour marinades and chutneys.

• Pickling: Malt vinegar is a great choice for pickling onions and other vegetables.

• Fries and roasted potatoes: In some Mediterranean countries, malt vinegar is used as a condiment for fries or roasted potatoes.
