(enough to make one jar – around 250-375ml)
- 1 Litre (4 cups) whole milk
- 300g caster sugar
- ½ tsp sea salt
- ½ tsp baking soda
- 1 tsp vanilla extract
- In a pot large enough to fit the liquid with at least 10-15cm from the top of the pot to the level of the milk, add milk and stir in the sugar, salt, baking soda and vanilla extract.
- Turn heat to med-high and bring the milk mixture to a boil without stirring. Once you see the milk start to boil and bubble slightly, get ready to turn the heat right down because the milk may froth and rise if it is overboiled.
- Once it’s boiled, turn the heat down to the lowest (until it’s barely a simmer) and skim the foam. Continue to simmer uncovered for around 2 – 2.5 hours, stirring constantly (around every 10 minutes or so is best if you’re free) and skimming the foam when necessary.
- 1: milk starts to foam as it heats up
2: getting frothy and rising as it boils
3: overboiling will cause the milk to rise fast (and spill over so be careful)
4: bringing it down to a simmer
It’s best to cook it as low and slow as possible. If the heat is too high, the milk will boil and form a skin that won’t disappear no matter how much you whisk it.
Check the consistency at about 2 hours. I usually stop it now when I want a runnier caramel to use in other recipes. Cook it a little longer if you want a thicker jam to use as a spread or to sandwich cookies. Just remember that it’ll thicken up more while it cools and when it’s in the fridge.
Top row L-R: starting to colour at about one hour; thickening up at around 1.5 hours; at nearly 2 hoursBottom row L-R: ta-da! Once it looks gloopy, it’s ready; checking consistency on the spoon; a frantic whisking will smooth things out!
Once it’s thick and gluggy and just about ready, you need to keep an eye on it to prevent it from scorching on the bottom of the saucepan. When it’s ready, take it off the heat and whisk the confiture until it’s glossy and smooth.
Pour into a clean jar and cool uncovered. When it has cooled completely, stick the lid on and store it in the fridge (it should keep for around 1 to 3 weeks).
