Trash Tiki Citrus Stock

"Trash Tiki"

ABOUT
_____

Trash Tiki is a pop-up and online platform dedicated to reducing waste
across the bar industry globally. And its citrus stock recipe, which
was conceptualized by co-founder Kelsey Ramage and partner Iain
Griffiths alongside Ryan Chetiyawardana in London bar Dandelyan's
juicing room, is a simple yet effective 30-minute process of pressure-
cooking spent citrus husks (pulp and all) in water, then straining and
adjusting with acid and sugar to produce a liquid that essentially
acts as a juice substitute or volume enhancer. It's a waste-reduction
and resource-doubling technique that offers something the usual
suspects (oleo saccharum, cordials, preserves, dehydrating for
garnishes, and the like) do not.

This recipe originally appeared as part of "Repurpose Your Citrus with
This Waste-Reducing Hack."

INGREDIENTS
___________

   51 oz  Water
2 1/5 lb  Citrus husks (halved and juiced)
       1  Large strainer (such as Superbag or chinois)
 1/3 cup  White sugar
          Citric acid*
          Malic acid*

DIRECTIONS
__________

Add the water and husks to a large pot and let boil for 5 minutes.

Remove the husks (your stock will go bitter if you leave any longer),
giving a quick squeeze back into the mixture as you pull them out.
Remove the liquid from heat quickly and measure. (Accounting for some
loss in heat evaporation and absorption from the husks, it should be
44 fluid oz, give or take).

Place back on high heat until liquid is reduced by 50 percent, then
add the sugar.

Add the citric and malic acid according to ratio based on citrus
type.*.

Remove from heat, filter, bottle and refrigerate.

*Acid ratios by based on citrus varieties: Lemon and lime: 3% citric,
2% malic Orange and grapefruit: 2% citric, 1% malic Mandarin, etc.: 1%
citric, 2% malic.

Note: This recipe can easily be scaled up or down based on how much
supply you're working with or the volume you're aiming to produce.
Citrus stock can be kept fresh for three days or frozen for one month.
