Not the recipe for Dr Pepper

I reviewed dozens of different ingredients that people speculate might be the 23 flavors in Dr Pepper. These are the ones I think are the least likely:

1 L water
1 L sugar

175g prunes
100g diced tomato
10g peppermint
10g unsweetened coconut flakes
5g prickly ash bark
3g wild cherry bark
3g birch bark
3g spikenard
3g mace
3g cacao nibs
2g cardamom
2g coriander
2g burdock root
2g gentian root
2g dandelion root
2g sassafras root

350 ml apricot
150 ml grape juice
50 ml carrot juice
30 ml maple syrup
20 ml honey

50 ml rum extract
Pinch of salt

Infuse spices into syrup of sugar and water. Mix with remaining ingredients

Makes 2 L of syrup. Mix with 10 L of carbonated water for soda
