Not really "lunch" but I made coffee for the first time ever. I've never been a huge coffee person, but I will occasionally get coffee from different places.
One of the coffee drinks I like is from the Blue Bottle chain, and it's their "New Orleans" blend. Not entirely sure what type of beans they are but it's that, some ground chicory, some sugar, and then milk. I decided to first try making a coffee I know I like, so that's why I went with this. Basically you cold brew the ground beans and chicory overnight in the fridge:
The bottle is a "Hario Mizudashi" cold brewing bottle.
Then after 12 hours, you can use the cold brew concentrate with ice, a little sugar, and milk (their milk spec is always too much at the stores, 4oz, so I only did 2oz):
