I am not a port drinker, though I can see the allure. However, I do have a great cranberry sauce recipe that I've made with either port or tequila (both work, but very different). Try it, you'll like it!! Super easy, and perfect this time of year (or for Turkey Day).
Cranberry Sauce with Tequila & Tangerines (also can be made with Port instead of Tequila)
1 (12-ounce) bag fresh or frozen cranberries
1/2 to 3/4 cup sugar - I like less sugar
1/2 cup Port or Tequila
3-4 tangerines zested
1/2 cup tangerine juice (from the tangerines)
Bring cranberries, sugar, and zest to a simmer in a small heavy saucepan over medium heat, stirring until sugar has dissolved. Simmer, uncovered, stirring occasionally, until cranberries burst, about 10-12 minutes. Remove from heat and stir in juice. Cool completely.
Can be made up to a week early & kept stored in fridge in airtight container.
