In a medium saucepan, combine chocolate chips and heavy cream and heat on low, stirring constantly until the chocolate is melted and mixture is smooth. Do not let come to a boil or chocolate might seize.
Once chocolate is melted, stir in vanilla extract and sea salt. If you need it to be thinner, add 1 tablespoon of heavy cream at a time until it reaches desired consistency. Pour mixture in fondue pot to keep warm.
Serve with dippers of your choice.
Use quality chocolate. The better the ingredients, the better the flavor.
Always melt the chocolate over low heat to avoid scorching and prevent it from seizing.
Melt the chocolate first over the stove before transferring to a fondue pot.
Brush cut-up fresh fruit with lemon juice to prevent oxidizing.
If the chocolate is too thick or lumpy, you can salvage it with a few teaspoons of vegetable oil.
