Very tangy, not too sweet! Heaven must taste like this. Got this from the NPR website, with a story about going to pick the apricots at the orchard every summer.
Note: I pack the apricot halves firmly into the measuring cup so they are bursting full when I measure them. If you don't pack them in as firmly, you might want to use a few more apricots. Also, a note about the serving size: this assumes you are using a tablespoon or so as a serving to spread on a piece of bread. In my experience, this recipe makes just less than a pint of jam.
