The cream on your cake with fresh pineapple may not set because the pineapple contains an enzyme called bromelain, which can prevent the cream from setting properly. Bromelain breaks down proteins, which can interfere with the structure of the cream and prevent it from thickening. To avoid this issue, you can try cooking the pineapple before adding it to the cream, as heat can deactivate the bromelain enzyme. Alternatively, you can use canned pineapple, as the canning process deactivates the enzyme. **
