3 steps, 3 ingredients and 30 minutes is all you need for this easy and delicious strawberry jam (no pectin added). This is my go-to recipe, which I love to make at the peak of strawberry season when this fruit is at its ripest. This jam is smooth, spreadable, and simply lets the strawberries shine.  A great small-batch recipe for first timers or any home cook to add to their repertoire.

A lower-sugar, no pectin added strawberry jam

This Strawberry Jam recipe requires only 3 ingredients: strawberries, lemon juice, and sugar– with no pectin added. You only need to cook the berries for as little time as they require to release their natural pectin and thicken. The sugar also helps to build thickness and acts as a natural preserving agent.

Different varieties of strawberries (including Gariguettes and Maras des Bois) at the market in my hometown, in Brittany, France.

Traditionally, jams account for an equal amount of fruit and sugar. But I found that cutting the sugar by almost half still makes for enough thickness. You could up the amount of sugar if you desire a thicker jam. However, I don’t recommend using less sugar or the jam will be too runny. 

Compared to store-bought jams or other berry jams, this jam is slightly less sticky as there is no pectin nor thickening agents added, and far less sweet as well. This makes for an easily spreadable jam, with a taste that allows the fruit to shine.  

Strawberries are plentiful in Brittany, from early Spring and all throughout Summer.

I have been making this strawberry jam recipe every Spring, for years now. Whether living in Niagara, Ontario or in Brittany, I have always been lucky to be in a place where local strawberries are plentiful in early Summer. So here are a few tips I learned along the years, to perfect this recipe (although you can definitely apply those tips for making any other fruit jams really).

My tips for making jam:

• Choose fruits on the riper side, but not soft. Making jam and marmalade is a great way to use up fruits that are slightly over-ripe. Know that the riper the fruit, the sweeter the jam will taste. However, they shouldn’t be soft, or they will taste off.
• Adjust sugar, to a point. With 2 ½ (500g) of sugar, I know it can be tempting to lower the amount of sugar in this recipe. But if you do so, you won’t be able to cook the jam to the desired thickness. The sugar acts as a preserving agent and a thickener. With not enough sugar, you will end up with a jam that is runny, and hence not easy to spread. You can up the amount of sugar to as much as 900g, to have equal parts of fruit and sugar. The jam will be sweeter and thicker too – for a texture closer to store-bought jams.
• Don’t walk away. When making jam, you should watch the look and temperature closely, rather than the time. The strawberries need to cook only until they release pectin and start to thicken – not a minute more. If you let the pot simmer for too long, the sugar will start to caramelize and become too overpowering in taste. So, the shortest cooking time possible will give the best strawberry flavor.
• Use a candy thermometer. This will make this recipe easier, especially if you’re a first time jam maker. We need to reach 223°F (106°C) and you’ll know for certain that the jam is ready. But if you don’t have one, don’t worry: you can use the plate test (see note below).  
• Small batch is best. Because a short cooking time will you the give best flavor, making jam in small batches is always best. I would say this recipe, using 2lbs (900g) of strawberries is great for one batch. If using more fruit, divide it in several batches.

To test for jelling

If you do not have a candy thermometer – place two or three small plates in your freezer before you start. When chilled, take the plate out of the freezer and drop a little spoonful of the cooked jam on it. Wait 1 minute and check the consistency: it should have thickened significantly to a jelly consistency. You can run a finger through the jam. If it doesn’t run back together, it’s ready. If it still looks too runny, keep the mixture at a simmer and try again later. Have 2 or 3 small plates or saucers ready in the freezer for several tests as you cook the jam to your desired thickness.

For jarring

For jarring, you can simply pour the jam into 3 x 8oz jars (ie. mason jars), and keep it in the refrigerator to enjoy for up to 2 weeks. Once the jam is jarred, it is best to wait at least 1 day before enjoying. This allows for the flavors to develop further and the texture to set entirely.

If you wish to keep the jam for longer, use a can-sealed method: I recommend this article which covers it all.

Ingredients

2 lbs (900g) strawberries, ripe
2 ½ cups (500g) sugar
1 lemon, juiced (ideally organic)

Instructions

Step 1 – Wash, hull and chop the strawberries in half.

Step 2 – Add them to a large saucepan or pot and add the sugar. Stir to combine, until the sugar coats all the strawberries. Turn the heat to medium and bring to a simmer. Add the lemon juice. Let simmer for about 15 minutes, stirring occasionally, until a candy thermometer reads exactly 223°F (106°C). If some foam rises up the surface when boiling, skim it away with a large spoon.

If you do not have a candy thermometer – place two or three small plates or saucers in your freezer. When chilled, take a plate out of the freezer and drop a little spoonful of jam on it. Wait 1 minute and check the consistency: it should have thickened significantly to a jelly consistency. If it still looks too runny, keep the mixture at a simmer and try again later. In the pot, the jam should have the consistency of syrup; it will thicken significantly as it cools. 

Step 3 – When ready, remove the jam from the heat and let cool to room temperature before pouring into jars or airtight containers.

The jam can keep for up to 14 days in the fridge in non-sterilized containers or jars and up to 3 months in sterilized jars.
