Ingredients for Mary Berry Raspberry Jam
The charm of this recipe lies in its short ingredient list. For a classic Mary Berry batch, you’ll need:
- 900g fresh raspberries – Choose ripe, plump berries for the best flavor. If out of season, frozen raspberries can be used without compromising quality.
- 900g preserving sugar – This sugar contains added pectin, which ensures the jam sets properly. Ordinary sugar won’t guarantee the same results.
That’s all it takes: just two ingredients. The simplicity highlights the natural sweetness and tartness of raspberries while ensuring the jam has a reliable texture.
Equipment You’ll Need
Having the right tools makes the process smoother:
- Large heavy-bottomed pan (stainless steel is ideal)
- Wooden spoon for stirring
- Potato masher (optional, to help break down berries)
- Sterilized glass jars with lids
- Sugar thermometer or saucers for testing
- Ladle and funnel for easy pouring
Step-by-Step Method
Step 1: Get the Jars Ready
The first and possibly most important stage in the jam-making process is to sterilize your jars. You will need to wash the jars and lids first with hot soapy water, rinse, and then put them in an oven which has been pre-heated to 140°C (120°C fan) for about 15 minutes. If you keep the jars hot upfront and then put hot jam in them, they should not shatter.
Step 2: Cook Up the Raspberries
Put your raspberries in a large pan and heat them up gently. They will give up their juice and soften as they warm. You can mash them up with a spoon or masher slightly if you would like a smooth jam, or keep them a little more chunky to capture the raspberries more!
Step 3: Add the Sugar
When the fruit is sufficiently soft, add your preserving sugar and stir gently over a low heat until the sugar has dissolved. Here is the most important aspect of your jam making; if you get the jam mixture to boil before the sugar has dissolved, it may crystallize later.
Step 4: Boil the Jam
Return the heat to high temperature to produce a vigorous rolling boil. It is during this boiling stage that the jam will thicken and become glossy. Boil for 4-5 minutes while carefully monitoring the pan to ensure against overcooking. The thermometer will read 105 degrees Celsius for setting point.
Step 5: Test for Setting Point
Not everyone has access to a thermometer, so a wrinkle test is a worthwhile alternative. Place a teaspoon of the jam onto a chilled saucer. After a few seconds, touch the jam with your finger – if you see wrinkles, your jam has reached the setting point. If not, boil for an additional 1-2 minutes, then test again to see if wrinkles appear.
Step 6: Fill the Jars
Turn off the heat, and skim off any foam from the jam. Using a ladle and a funnel, pour the jam into sterilized jars. Place lids onto the jars immediately to seal them and create a vacuum. Allow to cool completely before putting away for storage.
Tips for Perfect Raspberry Jam
Even simple recipes benefit from a few expert tricks:
- Use preserving sugar: Raspberries have little natural pectin, so sugar with added pectin is essential for a firm set.
- Don’t stir too much while boiling: Over-stirring can break down the natural structure of the jam, leading to a runnier consistency.
- Check the set early: Jam can overcook quickly, so start testing after 3 – 4 minutes of boiling.
- Warm jars are non-negotiable: Adding hot jam to cold jars risks cracking them. Always sterilize and keep jars warm until ready to use.
- Skim foam for clarity: Removing foam gives your jam a jewel-like finish, making it more visually appealing.
Storing Your Homemade Jam
When sealed properly in sterilized jars, Mary Berry’s raspberry jam can last up to 12 months in a cool, dark place. Once a jar is opened, it should be refrigerated and consumed within 2 – 3 weeks for the best flavor and freshness. The sugar not only sets the jam but also acts as a preservative, extending its shelf life.
Serving Suggestions
The beauty of Mary Berry’s raspberry jam lies in its versatility. Here are a few ways to enjoy it:
- Spread generously over warm scones with clotted cream for a traditional cream tea.
- Use as the filling in a Victoria sponge cake or Swiss roll.
- Swirl into Greek yogurt for a quick breakfast or dessert.
- Top pancakes, waffles, or crumpets for a sweet morning treat.
- Add a spoonful to cheesecakes or trifles for a tangy contrast.
- Warm slightly and drizzle over ice cream for a fruity sauce.
FAQs
Q1: Is it possible to use frozen raspberries instead of fresh ones?
Sure, frozen raspberries are equally effective. Make sure they are completely defrosted before cooking for the best results.
Q2: Is it necessary to have sugar for preserving, or can I use regular sugar?
It’s better to use preserving sugar since raspberries are naturally low in pectin. Regular sugar usually leads to a softer, more liquid jam.
Q3: What would happen if my jam stayed unset?
If it happens to be too soft, you might want to re-boil the jam for a short time with additional preserving sugar or a little liquid pectin.
Q4: For how long does home jam keep?
Jars sealed in the right way last up to a year in a cool, dark place. After unsealing, jam should be kept in the fridge and consumed within a few weeks.
Q5: Is it possible to lower the sugar content and still have a healthy jam?
It is not recommended to reduce the sugar as it plays a role in preserving the jam and in setting the jam. Alternatively, if you want less sweetness, you can select a low-sugar pectin blend for making jam.
