Making this DIY citrus stock is great for your pour-costs and<\/em> the planet. <\/h3>\n\n\n\n
\n\n\n\n

Citrus stock<\/a> entered the bartending subconscious in 2016 when Kelsey Ramage<\/a> and Iain Griffiths <\/a>founded (Trash) Tiki, an online platform that detailed how to reuse and upcycle common ingredients. The premise began as a way to make an essential component of cocktail-making (lemon and lime juice) more sustainable and to extend the life-cycle of citrus in bars. Ramage, who went on to found Trash Collective<\/a>, notes that lemons and limes are grown in only a few countries, which means that these humble citrus fruits generate a massive carbon footprint as they get shipped around the world. \u201cWe\u2019re trying to reduce the amount of usage because the fossil-fuel costs of transporting lemons and limes are so ridiculous,\u201d Ramage says. \u201cBut it\u2019s the one ingredient that every cocktail bar around the world uses.\u201d<\/p>\n\n\n\n

The citrus stock, when done correctly, doubles the amount of citrus juice per fruit and extends the life of the citrus by two or three days, provided it\u2019s refrigerated. Spent lemon or lime husks are blanched in boiling water, then removed after a few minutes (recipe follows). A sugar-and-acid blend is added to the water, and then combined with fresh juice. \u201cThis creates a stock juice blend that replicates lemon or lime juice very easily,\u201d Ramage says. (Note: The citrus stock recipe below is designed for lemons and limes; for other fruits, such as grapefruit, see Trash Collective\u2019s additional recipes<\/a>.)<\/p>\n\n\n\n

What are the things that can go wrong? As with any recipe, it\u2019s important to read through all the instructions carefully first. The most common mistake, Ramage finds, is that bartenders don\u2019t know how to blanch husks correctly, and will either add the rinds before the water is fully boiling or let them sit too long in the water. Both mistakes result in overly bitter, pithy liquids. <\/p>\n\n\n\n

Sometimes, where you make the citrus stock can result in subtle differences. \u201cI\u2019ve made this in a number of different countries,\u201d Ramage says. \u201cI find that smaller lemons or limes will have a tendency to be less bitter whereas the bigger hormone-treated fruits have a tendency to get bitter really quickly.  It’s a timing thing and you have to adjust the recipe as you see fit.\u201d<\/p>\n\n\n\n
