What is lemon used for in jams: The reasons for using lemon

Lemon is often used as an ingredient in the preparation of jams. But what exactly is it for? Here are the reasons why lemon is a key inclusion for jams:

1. Lemon acts as a natural preservative

Lemon is a powerful natural preservative for fruit due to its acidity. This means that when added to jams, it prevents their oxidation and extends their shelf life. Lemon is also a good choice for those who wish to avoid the use of synthetic preservatives in their jams.

2. Lemon helps set the jam

Setting is the crucial stage in the preparation of jams. If the jam is not pressed properly, it can become runny and unusable. Lemon is a crucial addition because it contains pectin, a natural substance that helps solidify jams and give them a homogeneous texture.

3. Lemon adds color and flavor to jams

Adding lemon can give the jam a nice golden color and add a slightly tart, refreshing flavor. This can be especially beneficial in sweeter fruit jams like strawberry or blackberry jams.

Lemon is an important ingredient in making jams. Indeed, its use brings a number of advantages in terms of preserving the jam. First of all, it is rich in citric acid, which makes it possible to increase its acidity level and, consequently, to reduce its pH. This acidity is a crucial element for the preservation of the jam, as it prevents the development of bacteria and molds which could alter the content. Then, the lemon contains pectin, a substance that allows the jam to gel. This feature gives the jam its characteristic texture and prevents it from being too runny. Lemon is also used as a natural preservative for better preservation of jam.

But how to use lemon in the preparation of jam? The easiest method is to add freshly squeezed lemon juice while cooking the fruit. It can also be added as a zest or wedges, depending on culinary preference. However, it is important not to add too much lemon juice, as this may alter the taste of the jam. It is recommended to use a small amount, which is between one and two tablespoons for one kilogram of fruit.

In short, lemon is a magic ingredient in jams. This citrus brings the acidity needed to preserve the jam and freeze the fruit. Used effectively, it helps to make the jam taster, while keeping it longer.

Why is the lemon mainly used for the preparation of red fruit jams?

Lemon is not a mandatory inclusion in all jams, but it is often used for jams of soft fruits, especially strawberries and blackberries. Here’s why:

– Red fruit jams tend to be very sweet, which can taste too sweet if the lemon is not present.

– Berries tend to be delicate and oxidize easily once picked, so adding lemon can help preserve them longer.

– Strawberries and blackberries are also fruits that have a low content of natural pectin, which can make it more difficult to take. Lemon is an excellent source of natural pectin and can help set the jam in place.
