Straight rhubarb is green tartness with little body, like vaping the stalk raw. Custard, vanilla or apple supply the sweetness the pie dish usually would, which is why virtually every bottle here is a duet.
The good versions keep the fight alive: sharp on the inhale, custard on the exhale, exactly like the sweet dissolving. If either side wins completely the recipe has failed, and those bottles do not last on our wall.
