How to make Frappuccino

The Frappuccino is one of the signature drinks of Starbucks, popular for its refreshing and rich flavors. Here is a basic method for making a homemade version, which you can adjust according to your personal taste:

**Basic Ingredients:**
1. **Coffee**: Freshly ground coffee beans or instant coffee.
2. **Milk**: Whole milk or plant-based milk (such as soy milk, almond milk, etc.).
3. **Sugar**: Add according to personal taste.
4. **Ice**: Plenty of ice cubes.
5. **Whipped Cream**: For topping (optional).
6. **Syrup**: Such as vanilla, caramel, hazelnut, etc., choose according to taste.

**Coffee Preparation Method:**
1. **Brew Coffee**: Brew the coffee powder with hot water in the right proportion, or use instant coffee powder.
2. **Cool Coffee**: Let the brewed coffee cool to room temperature.
3. **Mix Ingredients**: In a blender, add cooled coffee, milk, sugar, and ice. The ratio can be adjusted according to personal taste, generally recommended is 1:1:1 (coffee:milk:ice).
4. **Add Syrup**: Add syrup according to personal taste, such as vanilla syrup, caramel syrup, etc.
5. **Blend**: Use a blender to mix all the ingredients until they are fully combined and smooth.
6. **Pour into Glass**: Pour the blended Frappuccino into a glass.

**Whipped Cream Preparation Method:**

1. **Prepare the Whipping Siphon**:
- First, open the lid of the whipping siphon, ensuring the inside is clean and dry.
- Pour in an appropriate amount of whipping cream. Do not overfill the siphon, usually it is recommended to leave about one-third of the space for the nitrous oxide to mix well with the cream. Overfilling may affect the quality of the cream whipping and may cause the siphon to malfunction.

2. **Assemble the Whipping Siphon**:
- Screw the lid back onto the siphon tightly. Ensure a good seal to prevent gas leakage when releasing the gas. A loose lid may cause gas to escape, thus failing to provide enough pressure for the cream.

3. **Insert the Nitrous Oxide Charger**:
- Place the nitrous oxide charger into the charger holder. The charger is a small steel canister filled with nitrous oxide gas.
- Screw the charger holder onto the nozzle of the siphon until you hear a hissing sound. This indicates that the gas is being released into the siphon and mixing with the cream.

4. **Shake the Siphon**:
- Once the gas is released, you need to shake the siphon vigorously for a few seconds. This step ensures that the nitrous oxide mixes well with the cream. The gas dissolves in the cream, creating a light, fluffy texture when dispensed.

5. **Dispense the Cream**:
- Now you can dispense the cream. Hold the siphon nozzle downwards.
- Press the lever to release the cream. The gas will push the cream out, giving it a smooth, light texture.

6. **Store the Siphon**:
- If there is leftover cream, proper storage is crucial. Store the siphon upright in the refrigerator. Upright storage helps maintain the consistency of the cream and prevents gas from escaping. Ensure the cream remains chilled to maintain its texture and flavor. Proper storage can keep the cream fresh for several days.

7. **Dispose of the Charger**:
- After use, it is important to dispose of the charger correctly. Unscrew the charger holder and remove the empty charger.
