A flaw it the recipe
Hi - there appears to be a flaw in the Giardiniere Pickles recipe. At one point it says "Next, pour a thin layer of vinegar into the bottom of the hot, sterilised jars and add a bay leaf, a sprig of rosemary and a sprig of thyme." If you do that, the glass cracks as a result of temperature difference (I know, because I tried it last night just to make sure!). Either the vinegar needs to be heated, or the jars need to be rested until they are warm, not hot, neither of which is mentioned in the recipe.
