5tablespoonsunsalted butter(71 grams)(cut into cubes)
½cupplus 1 tablespoon heavy cream(room temperature or slightly warm)
½teaspoonkosher salt or flaky sea salt
½teaspoonvanilla extract
3tablespoonswhisky(like Suntory Toki & Nikki Coffey Grain)
Instructions
In a medium heavy duty stainless steel saucepan, add sugar. Cook over medium heat, stirring constantly with a wooden or heat-resistant spatula. Sugar will clump together at first, but will melt into liquid, about 5 - 6 minutes. Keep an eye on the color. It will start from light yellow to deep amber.
When it's deep amber color, turn off the heat immediately. Carefully whisk in the butter. The caramel will be bubbling. Once the butter is combined, slowly pour in the heavy cream while whisking constantly. Whisk until smooth. Some caramel may harden and stuck together on the whisk or on the saucepan. If there is a lot clumps, turn on the heat to low and melt back into the sauce. If there is only a tiny bit, don’t worry about it.
Stir in salt, vanilla and whisky. Caramel will thicken as it cools. Let cool at room temperature for at least 30 minutes. Transfer to an airtight glass container. Store in the fridge for up to 2 weeks.
To use, either use as it is or warm in the microwave for 10 seconds or so to bring back to very runny consistency. Drizzle on your favorite dessert.
Notes
For whisky, I used Suntory Toki. Pick a whisky that is inexpensive with a vanilla note and mild oak flavor. If you don’t want to buy a big bottle, try to find mini bottles of Suntory Toki from local liquor store.
I recommend using 3 tablespoons of whisky for the sauce. It sounds like a lot, but you will use the sauce in different things and you want the whisky flavor to be prominent.
