Canning mixed fruit is easy and makes a great beginner project. It provides you with a taste of summer all year, and can easily be adapted to what you have on hand. This time I had beautiful, BIG, nectarines
Mostarda di Cremona isn't actually a mustard, rather it's summer fruits preserved in mustard-infused syrup. Use a mix of peaches, pears, plums, apricots, nectarines, quince, cherries, citrus rind. Makes for a beautiful holiday gift.
