It's almost Halloween, and you know what that means - time for some fun themed cocktails! I first made this one for a Mixology Monday challenge a couple of years ago. I was still working in a biology lab at the time, so I was able to swipe a few props and supplies. The Mad Scientist is a Daiquiri topped with lemon foam (raw eggwhites are spooooky) and served with a dropper of Green Chartreuse. It's meant to be added into the cocktail, but you can pipette that delicious stuff right into your mouth - I won't judge!

Mad Scientist

• 2 oz. white rum (I used Bully Boy)
• 3/4 oz. simple syrup
• 3/4 oz. lime juice
• ~1/2 oz. Green Chartreuse
• 1 egg white
• 1 1/2 tsp. sugar
• 1 1/2 tsp. lemon juice

For foam: (Only use fresh egg whites when consuming raw, and be aware that there is a risk of salmonella.) Place egg white in the bowl of an electric mixer. Beat with the whisk attachment until slightly foamy. Add in sugar and lemon juice and beat until the mixture reaches desired consistency.

For cocktail: Combine rum, simple syrup, and lime juice in a shaker with ice and shake until very well-chilled. Double-strain into a beaker. Spoon lemon foam on top. Fill a disposable pipette with Green Chartreuse. Place pipette into the cocktail and serve.
