Jam was prepared from two strawberry cultivars, ‘Cardinal’ and A‐5344, which were suited to once‐over machine harvest. For jam manufacture, puree from ripe (R) and immature (IM) fruits were combined in the following blends: 25% R + 75% IM, 50% R + 50% IM, 75% R + 25% IM, and 100% R. Initially and after storage at 2°C for 6 and 12 months, jam color and flavor of all mixtures were acceptable. Jam made from 25 and 50% ripe fruit of A‐5344 had unacceptable color after 6 and 12 months, respectively, at 25°C. All jam stored at 35°C was unacceptable after 6 months. Color acceptability was more dependent on total anthocyanin content than the percentage of ripe puree used in jam manufacture.
