CRUSHED PINEAPPLE JAM

There are a thousand uses for a good pineapple jam: toast, muffins, ham glaze, roast chicken glaze, pork roast glaze, cookie fillings and many more. My first attempt at making fresh pineapple jam was not totally successful since it never really "set" and I ended up using it as ice cream topping. I think the acidity or sugar level in any given pineapple varies greatly, so it was hard to get the right pectin ratio, but that's just a guess.
.
Now I use this excellent, super quick and super tasty recipe for pineapple jam that calls for canned crushed pineapple. I'd like to say that I, normally, would never consider making jam from a canned fruit (I make jam from berries that grow around the house); but, pineapple jam is the exception and this one gets five stars from Hubby.

(1) 20 ounce can of crushed pineapple (sweetened)
unsweetened pineapple juice (see note)
3 cups white sugar
(1) 1.75 ounce box Sure Jell pectin powder
(or the equivalent of liquid pectin)

GET READY
1. Wash your jam jars and rinse well (dishwasher works well) keep jars hot.
2. Place your 2 piece jar lids in boiling water, then turn the heat to low and let
them sit in the hot water till you need them.
3. Measure 3 cups of sugar and set it aside.
4. Add enough pineapple juice to the crushed pineapple, to equal 3¼ cups. One 20 ounce can of un-drained crushed pineapple and one six ounce can of unsweetened pineapple juice equals 3¼ cups.
TIME TO MAKE JAM
Place the fruit + juice + pectin in a six quart, heavy bottomed saucepan and bring the mixture to a rolling boil over high heat. Add the sugar, all at once, and bring back to a full rolling boil (one that can not be stirred down) stirring constantly. Boil for one minute. Remove from heat and skim off (and discard) any foam that is on the surface of the hot jam. Ladle hot jam into jars, filling to within ¼" of the top.
With a clean, warm, damp cloth, quickly wipe off the rims of the full jars and put the two piece lids on. Process the jars in a hot water bath for 10 minutes. Remove and cool on the counter.

NOTE: Recipe makes five cups of jam.

NOTE: I keep individual (6 ounce) cans of unsweetened pineapple juice in the pantry for cooking, rather than a big jug that spoils before it gets used up.
.
NOTE: We don't care for jam that has big (unspreadable) chunks of fruit in it, so I pulsed the pineapple in the food processor a few times before I started cooking the jam. The final product still had a pineapple texture, but no hard chunks. I think next time I make this, I will put in a few chopped maraschino cherries for fun & color.
