So, what's the secret to thickening custard? It all comes down to temperature and time. When you cook your custard, the starches in the mixture start to break down, and the proteins begin to coagulate, thickening the mixture. But, if you cook it too long, or at too high a temperature, you'll end up with a curdled, scrambled mess - not exactly what you're going for.
One of the biggest mistakes people make when trying to thicken custard is rushing the process. They'll crank up the heat, or whisk the mixture like crazy, hoping to speed things up. But, this only ends in disaster - a thick, gloopy custard that's more like glue than gourmet dessert. The key is to take your time, and let the custard cook slowly, over low heat, until it reaches the perfect consistency.

Another trick to thickening custard is to use a temperature control. This can be as simple as using a candy thermometer to monitor the temperature of your mixture, or as fancy as investing in a thermomix - a kitchen gadget that can precision-cook your custard to the perfect temperature. Either way, the goal is to cook the custard slowly and gently, until it reaches the perfect consistency.
