Instead of the drink it was modeled on, the Orange Blossom, I call it the "Lorange Blossom." In Horizons, you may recall the citrus farm scene in the ride, where the smell of "loranges" were pumped towards the ride vehicle. It wasn't quite orange, but it was close. Well here's the Lorange Blossom.
2 oz London dry gin (although if you or your bar have it, Hendrick's would be best)
1 1/2 oz blood orange juice (regular orange juice will do in a pinch, but if using that, drop the OJ to 1 oz and add the tiniest splash of grenadine for color)
1/2 oz lemon juice (if using regular orange juice, boost this to 1 oz)
1/4 oz dry vermouth
dash of orange bitters
Build over ice in a double old fashioned glass and give a good stir with a bar spoon.
