In a small saucepan over medium-high heat, bring sugar and water to a full boil. Prevent sugar granules from collecting on the sides. Avoid stirring.
Once the entire surface of the sugar is boiling, add the lemon juice. Do not stir.
Boil for 3 minutes – until the sugar goes from clear to lightly golden.
Leave the burner on, remove the saucepan from the heat and whisk in 1 tbsp of vegan butter.
Put back on heat, boil and whisk constantly for 3 minutes.
Remove from heat and gradually whisk in ¼ cup of soy milk. Cook until it reaches a light caramel colour.
Transfer saucepan to an ice water bath. Whisk vigorously.
As the caramel cools it will thicken up, if it starts to get too thick add 1 tbsp of soy milk and continue to whisk. Add more soy milk and whisk if needed.
