What Is Gelatin Bloom Strength?

Bloom strength measures how firmly gelatin sets. Here's how the Bloom test works, what the grade scale means (bronze through platinum), and why the number matters when substituting one gelatin for another.

Gelatin Sheets vs Powder: What's the Difference?

Sheets and powder are chemically the same, but they're measured differently and have different bloom strengths. This page covers the grade comparison table, when each format is used, and the conversion math.

How Much Gelatin Per Cup of Liquid?

Reference ratios by desired texture — soft set through very firm — plus the variables that change how much you need: acid, sugar, dairy, proteolytic enzymes, and temperature.

Gelatin Bloom Strength — Plain-English Guide

Which bloom strength to use for panna cotta, gummy bears, mirror glaze, and stabilized whipped cream. Includes a grade table and worked conversion examples.

Gelatin Sheets to Powder Conversion

Convert any sheet grade (bronze, silver, gold, platinum) to grams of powder, accounting for both bloom strength and sheet weight. Includes common conversion scenarios.

Not sure what bloom strength your gelatin is?

The main calculator starts with a diagnostic step — answer a few questions about your gelatin and it identifies the likely bloom value before running the conversion.
