Step 1

Place a small saucepan over a high heat and add an inch of water. Bring to the boil and then reduce the heat to low.

Step 2

In a small bowl, whisk together the plant milk and the cornstarch. Set aside.

Step 3

Place the vegan mayonnaise and vegan butter in a heatproof bowl and sit it on top of the saucepan of simmering water. Whisk until the vegan butter is melted and the mixture is smooth.

Step 4

Add the plant milk/cornstarch mixture and continue whisking until the mixture has thickened to a smooth, glossy sauce. Don't worry if the mixture appears to split, just keep whisking and the mixture will thicken.

Step 5

Once the sauce has thickened, whisk in the remaining ingredients until smooth. Remove the bowl from the saucepan and serve warm.

Step 6

Note: Store any extra vegan hollandaise sauce in a jar in the fridge. When you're ready to reheat the sauce, spoon it into a heatproof bowl and place over a pan of simmering water again. Whisk until smooth.
