One thing that I found I can make myself that rather surprised me was pancake syrup. Unless you buy pure maple syrup, all pancake syrup is sugar, water, some flavorings and a whole bunch of chemicals. The only thing I don’t stock in my kitchen is the chemicals and that is not a bad thing.
1 cup brown sugar
A little less than 1/2 cup water
1/4 tsp maple flavoring, vanilla, cinnamon, nutmeg, you can really get creative with your flavorings
In a small saucepan, combine the brown sugar and water. Bring the mixture to a boil. Turn the heat to medium and simmer, two to three minutes. It may take a few batches to figure out just how long to simmer it to get the consistency you like. Keep in mind the syrup will thicken as it cools.
