Wash the blueberries, rinse them, and put them in the pan. Add the sugar and refrigerate overnight. Cuci blueberry, bilas, dan taruh dalam panci. Tambahkan gula dan dinginkan semalaman.

Using low heat, simmer the blueberry mixture from last night. Give it a stir every 15–20 minutes. Turn off the heat once the liquid has mostly evaporated. Let it cool, then put it in a jar. Dengan api kecil, didihkan campuran blueberry dari tadi malam. Aduk setiap 15–20 menit. Matikan api setelah cairan hampir menguap. Biarkan dingin, lalu masukkan ke dalam stoples.

The blueberry jam is ready to use! Spread it on your bread, pancakes, or waffles for breakfast.
Bon appétit! 😋 Selai blueberry siap digunakan! Oleskan pada roti, panekuk, atau wafel untuk sarapan.
Selamat makan! 😋

Note: If you want to keep it for a longer time (7–8 months as long as it's unopened), let the jam cool to room temperature, then transfer it to a jar, close the lid, and store it in the refrigerator or a cool, dry place. Jika Anda ingin menyimpannya lebih lama (7–8 bulan asalkan belum dibuka), biarkan selai dingin hingga mencapai suhu ruangan, lalu pindahkan ke stoples, tutup, dan simpan di lemari es atau tempat yang sejuk dan kering.
