+# How to Make a Gin Fizz
+
+**Alcohol consumption is harmful to health. Minors are prohibited from drinking.**
+
+Estimated Difficulty: ★★
+
+## Essential Ingredients and Tools
+
+Ingredients
+
+- Gin
+- Club Soda
+- Lemon
+- [Sucrose Syrup](../../condiment/蔗糖糖浆/蔗糖糖浆.md)
+- Ice Cubes
+- Fresh Green Leaves (Optional, for garnish)
+
+Tools
+
+- Manual Juicer
+- Cocktail Shaker (Optional)
+
+## Measurements
+
+Yield: One serving, approximately 350 ml (including ice)
+
+- Gin: 30–40 ml
+- Club Soda: 1 can
+- Lemon: 1
+- 1:1 Sucrose Syrup: 30–40 g
+- Ice Cubes: 100 g
+
+## Instructions
+
+Preparing the Lemon
+
+1. Cut the lemon in half (**with the knife perpendicular to the axis of the lemon**), and slice one slice from one half for garnish.
+2. Cut the remaining half in half again. Use the juicer to extract the juice from the four resulting wedges into a container for later use.
+
+Mixing (Without Shaker)
+
+1. Choose a glass; a transparent glass with a capacity of 350–400 ml is recommended.
+2. Place 100 g of ice cubes at the bottom of the glass.
+3. Pour in 30–40 ml of gin.
+4. Pour in 20 ml of lemon juice (add more or all of it if you prefer a sourer taste).
+5. Pour in 30–40 g of sucrose syrup.
+6. Stir well with a spoon.
+7. Place the reserved lemon slice on the rim or float it on top.
+8. Slowly pour the club soda along the inner wall of the glass until full (avoid pouring directly onto the ice to prevent excessive foaming and loss of carbonation).
+9. Gently lift and lower the spoon to mix the liquid evenly (do not stir in a circular motion to prevent excessive foaming and loss of carbonation).
+10. Place the fresh green leaves on the surface for garnish (optional).
+
+If you have a cocktail shaker, you can replace steps 2–6 with the following:
+
+1. Pour the ice, gin, lemon juice, and sucrose syrup into the shaker and shake thoroughly.
+2. Pour the shaken mixture into the glass (if the ice is too crushed, you may strain it out and add fresh ice cubes to the glass).
