Quick Answer
Pure (“tu”) pineapple filling is mostly pineapple, tangy and fibrous; winter melon pineapple filling blends in winter melon jam, so it is sweeter and smoother and costs less. Store unopened filling as the label says, refrigerate after opening and use it quickly, and freeze it in portions, stirring after thawing. When buying from a factory, confirm the pineapple-to-melon ratio, sweetness, pack size and storage conditions.
Two pineapple fillings compared
| Pure pineapple filling | Winter melon pineapple filling | |
|---|---|---|
| Main ingredients | Pineapple (often Taiwan’s native variety), sugar, maltose | Winter melon jam + pineapple, sugar, maltose |
| Taste and texture | Sweet-tart, strong pineapple, visible fiber | Sweeter, smooth, milder pineapple |
| Common uses | “Tu” pineapple cakes, pineapple egg-yolk pastry, tarts | Classic pineapple cakes, winter melon cakes, Chinese pastries |
| Cost | Higher | Lower |
From the 1970s, winter melon was cheap and easy to source, so winter melon pineapple filling became the norm; pure pineapple cakes have since made a comeback. Neither is “better”; choose by product positioning and price. For the history, see the story of pineapple cake.
Can pineapple filling be frozen?
- Unopened: store at room temperature or chilled as labeled, away from heat.
- After opening: press plastic wrap onto the surface, seal and refrigerate; use soon.
- Freezing: divide into single-use portions and flatten; after thawing, stir well and cook briefly if it weeps.
