It is hard to imagine that, on this forum of all places, we cannot produce an accurate Yellowhammer. Perhaps it's constantly evolving? I found this long winded version
Yellowhammer Recipe...
Ingredients
~1 gal. Orange Juice (I use Tropicana Pure Premium - No Pulp)
~6 oz. can Pineapple Juice
~600-800 mL white Rum (I use Barcardi Silver)
~300 mL Amaretto
Process
~Pour half the orange juice into a pitcher to reserve for use at the end of the process,
~Into the remaining orange juice in the original container add the Pineapple Juice, white Rum, and Amaretto,
~Stir to mix well,
~Add back enough of the reserved orange juice to refill fully the original gallon orange juice container,
~Replace the cap and shake gently to mix well,
~Write the current date on the side of the gallon orange juice container with a Sharpie pen,
~Put the Yellowhammer mix in a refrigerator and allow to age for 6 WEEKS (you can drink after two weeks but it will not be as 'ripe' - and drink before three months as it will be 'overripe' beyond that point).
~Serve in a tall glass full of ice cubes - and garnish with a slice of orange and a cherry.
