Espresso or Cold Brew Tonic

For about 8 months I couldn’t have a lick of dairy or soy. And I live for my morning pour over with whole milk or when I’m out, a cortado. Milk substitutes didn’t cut it, or still contained allergens. Enter the espresso or cold brew tonic which felt fancy but fool proof to replicate at home. While mostly back to cow milk, this continues to be a delightful summer pick me up.
