Okay, tried a new simmer this morning. I just sliced up about half of a lemon and a lime.
Then I threw in some ginger. We buy a big thing of ginger*, grate it all with the food processor, then freeze it. So I just took out a hunk of it and threw it in the pot.
Then I poured in 1/2 tsp. of vanilla. It was a good one! So simple, and so fresh smelling, without smelling like Christmas. The kids liked it, too.
*We process our garlic this way, too. Buy a bunch, peel it all at once, process it, and then freeze it. We freeze garlic and ginger in gallon size freezer bags, laying flat. Then you can just break off what you need. Works great!
