Junket tablets vs rennet tablets: what's actually different comes down to strength not name. Junket is a dessert grade coagulant, cut with salt, starch and stabilizers. Real cheese rennet runs closer to 80% chymosin, the enzyme that builds a firm, age worthy curd.
Junket Tablets vs Rennet Tablets: Key Differences at a Glance
The gap starts with the enzyme itself. Cheese rennet runs about 80% chymosin and 20% pepsin. Junket flips that ratio, closer to 80% pepsin (New England Cheesemaking Supply Co., 2025).
Weaker stuff. More pepsin means faster protein breakdown: fine for a same day custard, rough on anything meant to age.
Junket tablets vs rennet tablets, side by side:
| Attribute | Junket Tablets | Rennet Tablets (cheese grade) |
|---|---|---|
| Enzyme mix | Mostly pepsin, plus salt, corn starch, and other fillers | Mostly chymosin, built to set a firmer curd |
| Best for | Custard, ice cream, quick fresh cheese | Any cheese, fresh through aged |
Junket's ingredient panel also lists salt, calcium lactate, corn starch, tricalcium phosphate and calcium stearate. A lot of extras. Cheese grade rennet tablets skip most of that filler and typically cost a bit more per box.
Which One Should You Choose
It depends on what's in the pot.
Choose Junket Tablets if…
- You're making custard, junket pudding or homemade ice cream (its original job)
- You want a fast, fresh cheese like paneer or a soft farmer's cheese not something you'll age
- You'd rather grab it at a regular grocery store than order specialty rennet
Choose Rennet Tablets if…
- You're making any cheese you plan to age, even briefly
- You want a firmer curd without added stabilizers or corn starch
- You make cheese often enough that a dedicated coagulant is worth ordering
Bottom Line
For desserts, Junket is the right tool: it's what the tablets were built for. For aging cheese, skip it. That's what's actually different in junket tablets vs rennet tablets: convenience against real cheesemaking strength.
Junket and rennet tablets clot milk at very different strengths so a dose that works for one will be wrong for the other. This tool turns either one into an exact liquid rennet amount by brand and batch size. Rennet Tablet to Liquid Converter
