Bars with nougat and caramel puff because the nougat is a whipped, aerated candy that expands under vacuum. Milky Way, 3 Musketeers and Snickers are popular. The chocolate coating does not puff; it softens and cracks around the expanding center.
Solid chocolate is mostly fat and sugar with almost no water. It melts on warm shelves and does not puff.
Prep and loading
- Cut bars into 1 inch bites.
- Place on a lined tray with space between.
- Use candy mode or warm shelves.
How to tell it’s done
- Bites are puffed and crunchy in the center.
Not sure? The weight check compares two weighings and the expected dry weight for candy bars.
Problems and fixes
Chocolate puddles
Solid chocolate or too much heat. Stick to nougat bars and lower the temperature.
Rehydrating and storing
Rehydrate: Not rehydrated.
Store: Sealed pouches. The chocolate can bloom (turn grey) over time; it is still safe.
Ways to use it
- Treat bags
- Ice cream topping
- Market sales
How much fits per batch
At a normal single layer, candy bars load at roughly 1 lb of fresh food per square foot of tray. That works out to:
| Machine | Fresh per batch | Dried per batch |
|---|---|---|
| Harvest Right Countertop 360 | 2.5 lb | 2.41 lb |
| Harvest Right Small | 3.0 lb | 2.92 lb |
| Harvest Right Medium | 4.7 lb | 4.54 lb |
| Harvest Right Large | 7.7 lb | 7.45 lb |
| Harvest Right X-Large | 15.6 lb | 15.15 lb |
