Few things beat the taste of homemade raspberry jam—sweet, tangy, and bursting with flavour. Whether spread on toast, dolloped into sponge cakes, or swirled into yoghurt, raspberry jam is a classic preserve that’s easy to make and loved by all.
Raspberries are naturally soft, full of flavour, and relatively high in pectin, making them ideal for beginners and seasoned jam-makers alike.
In this ultimate guide, you’ll discover:
- A foolproof UK raspberry jam recipe
- Ingredients, ratios, and variations
- Preserving and storage tips
- FAQs to help you get the perfect set
- Creative ways to use raspberry jam in your kitchen
Let’s get jammin’.
? Ingredients for Raspberry Jam (Makes 4–5 Jars)
| Ingredient | Quantity |
|---|---|
| Fresh or frozen raspberries | 1kg |
| Granulated or jam sugar | 1kg |
| Lemon juice (optional) | 1–2 tbsp |
Notes:
- Granulated sugar works well for fresh raspberries, especially if adding lemon juice
- Use jam sugar (with added pectin) for a firmer set or if using overripe fruit
- Frozen raspberries work just as well as fresh
? Step-by-Step Guide: How to Make Raspberry Jam
? Step 1: Prepare Your Jars
- Wash jars and lids in hot, soapy water
- Rinse well and place in an oven at 120°C for 15 minutes
- Alternatively, use a dishwasher on a hot cycle
- Let the jars cool slightly before filling
? Step 2: Heat the Raspberries
- Place the raspberries in a large pan
- Gently heat for 5–10 minutes to release juice
- Stir occasionally and lightly mash to break up large fruit pieces
? Step 3: Add Sugar and Dissolve
- Add the sugar (1kg)
- Stir over low heat until completely dissolved
- Add lemon juice (1–2 tbsp) to help the set and preserve colour
? Step 4: Boil to Setting Point
- Bring the mixture to a rolling boil
- Boil hard for 4–5 minutes, stirring often
- Use a sugar thermometer to reach 105°C, or do the wrinkle test:
- Place a teaspoon of jam on a cold plate
- Let sit for 1 minute
- Push gently—if it wrinkles, it’s ready
? Step 5: Jar the Jam
- Remove from heat and let sit for 1–2 minutes
- Skim off any foam
- Carefully ladle into warm, sterilised jars
- Wipe rims and seal with lids
- Label and allow to cool at room temperature

? Top 10 FAQs: Making Raspberry Jam
1. Do I need jam sugar or can I use granulated sugar?
Granulated sugar works fine if your raspberries are fresh and you add lemon juice. Jam sugar (with added pectin) helps achieve a firmer set faster.
2. Can I make raspberry jam with frozen fruit?
Yes! Defrost completely first and drain any excess water before cooking.
3. Do I need to strain the seeds out?
No, but if you prefer raspberry jelly, you can strain through a muslin cloth after simmering the fruit.
4. My jam didn’t set—what do I do?
Re-boil with a bit more lemon juice or add a small amount of jam sugar to boost pectin.
5. How do I sterilise jars properly?
Wash in hot soapy water, rinse, then heat at 120°C in the oven for 15 minutes. Alternatively, use a dishwasher’s hot cycle.
6. Can I reduce the sugar?
Reducing sugar will affect set and shelf life. Look for specific low-sugar jam recipes using special pectin.
7. Is this jam vegan?
Yes—it’s fruit, sugar, and lemon juice only.
8. How long does it last?
Unopened in a cool cupboard: 6–12 months. Once opened, keep in the fridge and use within a month.
9. Can I freeze raspberry jam?
Yes—use plastic containers or freezer-safe jars. Leave room at the top for expansion.
10. What’s the difference between jam and jelly?
Jam uses whole fruit or crushed fruit. Jelly is made from strained fruit juice for a seedless, clear spread.
