Yes, you can sieve jam, particularly to remove seeds.
While not always mandatory, using a sieve is a method employed by some jam makers. The primary purpose, as highlighted in the provided reference, is to create a smoother jam by filtering out seeds.
Why Sieve Jam?
Based on the reference, using a sieve offers a practical way to improve the texture of certain types of jam.
- Seed Removal: A sieve helps filter out many of the seeds from the fruit mixture. This is particularly useful for fruits with numerous small seeds, like raspberries or blackberries.
- Texture Improvement: By removing seeds, the resulting jam often has a smoother mouthfeel, which some people prefer.
The Outcome of Sieving
It's important to note that, as the reference states, using a sieve "you won't get 100% seedless jam". However, it is an effective tool for significantly reducing the seed content.
In summary, while not every jam requires sieving, it is a valid step you could also use if you have the equipment and desire a less seedy product. The reference explicitly mentions this possibility, indicating it's a known technique in jam making.
