With two lemons, remove the zest with a grater or a special device. (I float off). Try to remove only the yellow part, no white, white can add unwanted bitterness.

And a squeeze of lemon juice. Juice should be 200 ml, i.e. if not enough of two lemons, take the lemons yet. Depends on juiciness, size, type and age of the fetus. It took me 2.5 lemon juice.

Into the bottle pour the vinegar, lemon juice and zest. Insist 2 weeks in a dark place. Periodically shake the bottle.

After 2 weeks, the vinegar is filtered and pour into a clean bottle. Stored in a dark place. We've got a great base for salad dressings, it only remains to add olive oil, freshly ground black pepper and other seasonings and spices to taste (mustard, for example). I also really liked the grilled trout I had pepper and misted it with vinegar and left to marinate for 30 minutes, then fried on the grill. It was very tasty.
