Using Heavy Cream (US) Instead of Double Cream
Ratio
1:1
Excellent — nearly identical results
Recipe Adjustment Notes
The standard swap in each direction. Pouring and cooking uses are identical; whipped heavy cream sets slightly softer, and for very rich ganache the lower fat reads marginally lighter.
The Science Behind This Swap
The 10-point fat gap (48% vs 36-38%) matters at the extremes — whipping stiffness and split risk in boiling sauces — but not in everyday baking.
Measurement Variance Note
For 1 cup references, this ingredient can vary by about 6% across brands and measuring methods (223g-251g per cup). For the most reliable substitution result, measure by weight and test a half batch first.
