Chop your plums roughly and add them to a medium sized saucepan.

Add the sugar & lemon juice, and give the mixture a quick stir.

Place the saucepan over medium heat.

While stirring occasionally, bring the fruit mixture to a boil.

Boil for about 10 minutes, while stirring periodically, until soft and jammy.

Once cooked, remove from the heat. Using a potato masher, mash the remaining fruit pieces.

Next, take a fine mesh sieve and place over a a medium sized mixing bowl. Pour the cooked fruit into the sieve. Using a rubber spatula, scrape the fruit through the sieve, releasing the juices and keeping the pulp.

Discard the pulp (or eat over yogurt, like I like to do!).

Let the reduction cool, and place into an airtight storage container. Refrigerate.

Use within 3-5 days.
