The main effect of Hot and Cold drinks is the temperature difference of the drink. Half of it is hot, and the other half is cold; by appearance, it should not look different from a regular drink, for example, tea or sake. The patron should not suspect anything different just by looking at it, as the main effect is the sensory surprise after tasting the beverage. The brain is getting conflicting information from the sensory cells. Is it hold or cold, and there are few seconds of shock, indecision, and confusion, as the person doesn’t know how to react to the unexpected taste.
I use Agar-agar to create this type of experience as it can turn jellified substance into a fluid gel when stirred. If you wonder what Agar is, it is a mix of carbohydrates extracted from seaweed, Red Sea algae. In Japan, it is known as Kanten, and it has been in use since the late 1600s. Agar-agar has almost zero calories, no flavor, odor, or color; it is also sets at room temperature, and unlike Gelatin, it is suitable for vegetarians. Agar is used to make jams and jellies, ice cream, and other desserts in culinary.
The method In the recipe below can be applied to any drink; there are probably some other ways of creating the same sensory experience; experiment and have with it.
Raspberry Lychee Sake - Half Cold Half Hot
Sake served hot and cold in the same glass.
- 1 oz Sake
- 1 oz Vodka
- 7 oz Lychee juice
- 1 oz Raspberry syrup
- 2 oz Agar
- Dissolve the agar for a few minutes in a bit of Lychee juice.
- Add the rest of the ingredients.
- Boil it - a high temperature is necessary for the gelling process.
- Once boiling is done, put it on a side, it will become a firm gel, usually within a few minutes.
- Wait until it cools down and put it in the fridge, as we need part of the drink to be cold.
- When it is ready, take some of it and heat it. It takes me around 20 seconds to get the right temperature and texture in my microwave.
- Take the same amount of agar gel from the fridge and whisk it or blend it to become a fluid gel.
- Use sake or similar glass for the drink.
- Insert a divider in the middle of the glass and slowly pour the hot and cold sake on each side.
- After carefully removing the divider, the gel part of the drink will hold the warm part of the drink.
- Timing is important as the hot agar sake base will start slowly jellifying in about 10-15 min.
Different Agar products might need an adjustment of the amount need it. I bought one time flavored Agar from an Asian store, and I had to increase the amount to 2.5 gr, 0.8% of total liquid volume, to make it work.
