Syrup. I grew up not knowing what commercially sold syrup tastes like. I learned the 2:1 ratio as soon as I started cooking.
2 c. sugar
1 c. water
Bring to a boil. Add flavoring.
4 c. sugar
2 c. water
2 T. corn starch
Fresh or frozen berries 1/2-1 c.
Mix sugar and cornstarch in pan.
Add water, and heat to a boil, stirring occasionally. Add berries, bring to a boil again. Let boil for 2-3 while stirring. Syrup will continue to thicken as it cools.
