This one is a bit too sweet and intense as written. I tried replacing the lemon juice with lime juice and the result was noticeably better balanced, allowing the basil and the limoncello's herbal notes to shine through.
Due to me being unable to find melon liqueur anywhere in my country I went ahead and made my own (on a base of white rum). Perhaps my version ended up way different from a bottle of Midori, but this cocktail quickly became one of my favorites. Delightfully sweet and sour, reminded me of sour fruit candy.
