Weck glass jar, cylindrical, to make preserves at home. 340ml capacity. The 340ml Weck cylindrical glass jar is very suitable for making canned vegetables, pickles, compotes, fruits in syrup, etc. But not only to make preserves, you can use it to store all kinds of food or prepared food, freeze, etc. Store legumes, cereals, pasta, sugar, cocoa, pickles, pickles, sauces, etc. Dehydrated foods can be stored, since they are completely sealed and moisture does not enter, as well as already fermented foods. Bake food inside the jar: in the traditional oven or in the microwave. Freeze: in this case, as in any other jar, we must be careful to leave a little free space to avoid breakage when the food expands when frozen. It is advisable to avoid sudden changes in temperature: if we have put the hot food in the jar, we must let it cool before putting it in the freezer. Transport food (potted salad, ready-to-heat dishes, soups or creams without danger of spilling, desserts...). We don't need lunch boxes, the jar is the perfect container.
