Base recipe

Salty plum syrup

If you only make one thing from this site, make this. Salty plum syrup turns a difficult-to-measure fruit into a pourable, consistent ingredient. Fifteen minutes of work gives you a bottle that will carry a dozen sodas, mocktails and cocktails.

Makes

1 cup

Rows of homemade preserve jars on a wooden shelf

Ingredients

  • 150 g seedless salty plums, roughly chopped
  • 200 g white sugar
  • 250 ml water
  • 1 strip lime zest (optional)

Nail the ratio

The 3:4:5 rule — 150 g plums to 200 g sugar to 250 ml water — is easy to scale. Double it for a big batch.

Method

  1. 01

    Combine the chopped plums, sugar, water and lime zest in a small saucepan.

  2. 02

    Bring to a gentle simmer over medium heat, stirring until the sugar dissolves.

  3. 03

    Simmer for 8 to 10 minutes until the liquid is slightly thickened and tastes strongly of plum.

  4. 04

    Take off the heat and let it steep for 10 minutes.

  5. 05

    Strain through a fine sieve, pressing the fruit to extract every drop. Keep the solids for ice cream.

  6. 06

    Cool, then pour into a clean bottle and refrigerate for up to two weeks.

Serving suggestions

  • Soda: 20 ml syrup, a squeeze of lime and soda water over ice.
  • Lemonade: 30 ml syrup per glass of cloudy lemonade.
  • Cocktails: use it in place of simple syrup in a gin sour, margarita or spritz. See the cocktail guide.
  • Dessert: spoon over vanilla ice cream or drizzle on pancakes.

Variations

Gingered

Add 4 thin slices of fresh ginger to the pan for a warming kick.

Vanilla plum

Split half a vanilla pod into the simmer for a rounder, softer syrup.

Less sweet

Drop the sugar to 150 g. The syrup is thinner but noticeably more sour.

Frequently asked

How long does it keep?+

Around two weeks in the fridge in a clean container. The high sugar content helps, but it is not a true preserve.

Can I use whole plums with stones?+

Yes, but pit them first. Simmering stones will not do the flavour any favours.

Can I use a sugar substitute?+

Some sweeteners work in syrup, but they do not thicken or preserve the same way. Expect a thinner result and a shorter shelf life.
