Traditional recipes call for combining sugar and water in a pan, stirring to dissolve the sugar as it heats and brushing down the inside walls of the pot with a wet pastry brush to prevent crystallization.
But with our method, you add the sugar after the water, pouring it right into the middle of the pan, making stirring not only unnecessary but also undesirable.
Increasing the proportion of water to sugar prevents the sugar from traveling up the sides of the pot, making brushing down the sides also unnecessary.
To keep the caramel from turning grainy, incorporate corn syrup: The sucrose molecules of white sugar have a strong tendency to cling together in larger grains, but incorporating corn syrup (which contains glucose) “dilutes” the sucrose molecules and keeps them separate.
