5. Mixed cooking: Mix the sweet potato paste and apple jam together in a heating pot, heat slowly and stir continuously, control the temperature above 104°C, and stir-fry until it forms into lumps.

6. Shaping: Spread the fruit-sweet potato mixed jam on a flat baking tray coated with lard, coat the surface with another layer of lard, then press into thin pieces about 0.4 cm thick.

7. Baking: Send the thin pieces into a dryer and dry them at 60 [degrees], then turn them over to dry the bottom after the surface is dry. The moisture content after drying should not exceed 12%.

8. Finished product packaging: Cut the finished product into square pieces, stack them neatly, wrap them tightly with cellophane, then seal them with a packaging bag or packaging box, and they are ready for market.
