⭐ Coconut Cream (Best Vegan Option)
1 cup coconut cream per 1 cup heavy creamCoconut cream contains a high fat content (around 20-25%) and thick consistency, making it a good emulsifier and textural match for heavy cream in Béarnaise sauce. The fat stabilizes the emulsion formed with egg yolks and butter.
Use full-fat coconut cream chilled and well-stirred to avoid separation. Be mindful of the coconut flavor, which can complement or clash with the tarragon and vinegar depending on your palate.
The sauce will be rich and creamy but with a noticeable coconut undertone, which may be desirable in some fusion variations but less traditional.
