Step-by-Step Instructions
First, let’s set ourselves up for a clean escape. I line my 8×8 inch pan with parchment paper, making sure there’s enough overhang on two sides to form a sling. This is my non-negotiable first step—trying to pry set fudge out of a bare pan is a lesson in frustration I only needed once. Now, in your heavy-bottomed saucepan, combine the white chocolate chips, the entire can of sweetened condensed milk, and the butter. Place this over the lowest heat setting your stove has. Patience is your secret ingredient here.
This is the gentle melting phase where you need to be present. I stand by the stove with my rubber spatula, stirring almost constantly and scraping the bottom thoroughly. White chocolate can seize and turn grainy in a heartbeat if it gets too hot. You’re waiting for it to melt into a completely smooth, glossy, and thick pool. When there’s not a single chip left and the mixture is velvety, I immediately remove the pan from the heat. The smell is wonderfully sweet and milky at this point.
Now, for the magic that makes this fudge special. Off the heat, I vigorously stir in the fresh lemon juice. Don’t be alarmed if the mixture seizes slightly and thickens dramatically the moment the juice hits it—this is completely normal! I learned this the hard way, thinking I’d ruined my first batch. Just keep stirring with faith; it will come back together into a thick, luscious consistency. Then, I fold in the finely grated lemon zest, the pure vanilla extract, and that pinch of salt. The zest is non-negotiable—it gives those tiny bursts of intense lemon oil that make the flavor sing.(See the next page below to continue…)
