Why It Happens
Freezing time is the most underestimated variable. At 12 hours the core may still be slushy (blade spins without scraping). At 24 hours the block is uniformly solid — the ideal state. Beyond 48 hours in a cold freezer, blocks over-harden and strain the motor.
How to Fix It
- Base still slushy at 12h? Wait — a partially frozen base processes into soup.
- Standard: 24 hours at -18 C on a flat shelf.
- Container stored 48h+ or in a -25 C freezer: let sit 10-15 minutes at room temperature first.
- Meal-preppers: freeze multiple containers, they hold perfectly 2-3 weeks before processing.
How to Prevent It
- Set your freezer to -18 C: the sweet spot for 24h freezing.
- Plan ahead: prepare bases in the evening, process the next evening.
- Sencor official manual states 12-24h; ICED Method testing confirms 24h gives the most consistent results.
Frequently Asked Questions
Can I process after only 12 hours of freezing?
Risky. The Sencor manual allows 12-24h, but at 12h the core is often still soft, producing soupy results. ICED Method testing across all machines shows 24h delivers consistent, scoopable texture.
Is 48 hours or a week in the freezer a problem?
No for storage, but the block gets harder over time as crystals reorganize. After 48h+, rest the container 10-15 minutes at room temperature before processing.
Does freezing faster improve texture?
Yes — faster freezing creates smaller ice crystals. Place containers in the coldest zone (bottom shelf, back), never in the door.
