Every morning my husband wakes up, fills the french press with coffee and boils the water. He fills his travel mug and leaves for work leaving behind almost exactly one more cup of coffee. I don't drink coffee, can't stand the stuff. My husband won't reheat old coffee. So every day I was pouring money down the sink in the form of this wasted cup of coffee. Granted it is still cheaper than a trip to Starbucks every morning, but still. Waste not want not is a motto I was raised on. I started to freeze the stuff, thinking I'd find a use for it eventually, and then, I had a big duh moment.
My husband also likes the iced coffees that Starbucks offers, with the names like frappacino, for $2.50 a bottle. So one day I poured the leftover coffee into a jar. I used a salsa jar, you could use a recycled frappacino bottle from Starbucks. I added sugar (Organic evaporated cane juice actually) , I added cream. I put the lid on and shook it all together before putting it in the fridge. Then I slipped it into his lunch box the next day.
He tells me it tastes good. Almost exactly like the store bought version in fact. He's been taking it every day since and has been enjoying an iced coffee at lunch out of what was essentially waste before.
