Calculators & Tools

A suite of interactive calculators for frozen dessert production. Each tool runs right in the docs to help you balance formulas, hit texture targets, and scale recipes with precision.

• PAC Calculator

Balance sweeteners for freezing-point depression. Aim for the 240–280 PAC band for a scoopable base.

• Fat Calculator

Dial in dairy and yolk ratios. Fat drives creaminess, body, and how easily a base whips up air.

• Overrun Calculator

Measure or predict air incorporation by volume or weight to control density and yield.

⚖️ Batch Scaler

Scale the Lean base up or down with measurable rounding and per-unit subtotals.

• Brix Converter

Measure Brix or solve for the sugar (or water) needed to reach a target for sorbets and granitas.

• Unit Converter

Convert weight, volume, and temperature for consistent, repeatable measurements.

Calculator Theory

Understanding the science behind these tools helps you make better formulation decisions.

PAC (Potere Anticongelante)

PAC values represent the freezing-point depression power of different sugars on the sucrose = 100 scale. Key concepts:

• Molecular weight relationships and colligative properties
• Multi-sugar interactions (dextrose and invert depress more than sucrose)
• A balanced base lands in the 240–280 target band

Overrun Science

Overrun is the percentage of air incorporated during churning:

• Formula: ((Churned volume − Base volume) / Base volume) × 100
• Affects texture, melting behavior, and mouthfeel
• Optimal ranges vary by product type (denser for gelato, lighter for commercial ice cream)

Fat Balance

Fat content affects:

• Creaminess and richness
• Melting characteristics
• Stabilizer effectiveness and air retention

Using Calculators Effectively

Best Practices

1. Verify inputs — double-check measurements and units
2. Consider temperature — many calculations are temperature-dependent
3. Account for variability — natural ingredients vary in composition
4. Test and adjust — calculators provide starting points; fine-tune by taste and texture

Common Pitfalls

• Ignoring water content in ingredients
• Not accounting for alcohol’s effect on freezing point
• Over-relying on calculations without sensory evaluation
• Forgetting to recalculate when changing suppliers

Integration with Recipes

These calculators work alongside the recipes in this documentation:

1. Start with a base recipe
2. Use the calculators to adjust for your needs
3. Document your modifications
4. Scale confidently for production
