What makes restaurant rice sticky is how much water is used in the cooking process of the rice as well as the type of rice used and the way the rice is cooked.
For example short or medium grain rice varieties such as the ones used in Chinese Cuisine, Vietnamese Cuisine and Thai Cuisine naturally have higher amylopectin content that contributes to the rices stickiness when it's cooked.
Also methods such as soaking the rice before you cook the rice and also using precise water rations can also enhance the sticky texture of the rice when cooked.
These are common methods that restaurants use when cooking rice to make their rice sticky.
To reduce the taste of vinegar in rice you can use some sugar and salt in addition to the rice vinegar which adds a balance of salt and sweetness.
And also rinsing the rice thoroughly before you cook the rice can also help remove some of the flavor of the vinegar in the rice.
Another way to reduce the taste of vinegar in rice is to add a bit of baking soda which will react with the vinegar's acid and neutralize it and create CO2.
When adding any vinegar to rice including white vinegar or rice vinegar to rice you add the white vinegar or rice vinegar to the rice after cooking the rice.
Rice vinegar or any other vinegar should be added to the rice after cooking but while the rice is still warm to allow the rice to absorb the rice vinegar better and absorb the vinegar's flavor and also help evaporate any moisture.
Allow the rice to cool just a bit but not quite to room temperature and then add in the rice vinegar.
Adding in the rice vinegar during cook can cause the rice vinegar to evaporate and affect the flavor and texture of the rice.
The amount of rice vinegar that you need for 2 cups of rice is 1/4 cup of rice vinegar which also equates to 3 tablespoons of rice vinegar.
This amount of rice vinegar is often used in recipes for making sushi rice.
For making standard sushi rice, a common ratio of rice vinegar to rice is 1/4 cup of rice vinegar per 2 cups of rice.
If using rice vinegar for seasoning cooked rice for other types of rice dishes, you can adjust the amount of rice vinegar according to your own preference and some recipes also suggest 1/4 cup of rice vinegar to 1 cup of cooked rice.
And when you're making sushi rice you also need sugar and also salt and a common ration of sugar and salt and rice is 3 tablespoons of sugar and 2 teaspoons of salt for 2 cups of rice.
And after the rice is cooked, you then combine the vinegar, salt and sugar in a separate pan, and bring it to a simmer until the sugar and the salt has dissolved and then you add it to the cooked rice and mix it in.
Adding vinegar to rice also reduces it's glycemic effect which means that when vinegar is added to rice it means that the rice won't spike your blood sugar levels as much as it would without the vinegar added to the rice.
The effect of vinegar in cooking rice is that the vinegar helps to break down starches in the rice and prevents the rice from sticking together when cooking and also results in fluffier and more separate grains for rice.
The acid in the vinegar when added to cooking of rice also helps the rice absorb more moisture and leads to a firmer, tender texture and also prevents spoilage.
To add vinegar to rice to avoid spoilage you can add a small amount of vinegar to the rice either while cooking it or after cooking it.
During cooking you can add a teaspoon or less of some white vinegar for each cup of rice to the rice during cooking.
While you add the vinegar to the rice while cooking you stir the vinegar into the boiling water before adding the rice.
If making sushi rice, you can add a specific mixture of rice vinegar, sugar and salt after the rice is cooked.
For sushi rice, the vinegar mixture is added to the hot rice and stirred into it thoroughly.
The acidity of the vinegar prevents spoilage of the rice by inhibiting bacterial and mold growth which are the main causes of rice spoilage.
When washing rice you are supposed to wash the rice until the water is clear.
Washing or rinsing the rice until the water runs clear is a a common practice when preparing rice for cooking.
When you rinse or wash the rice until the water runs clear it helps remove any excess starch and debris from the rice, which results in the rice being fluffier and also less sticky when cooked.
Some people avoid rinsing the rice or washing the rice until the water is completely clear, but it's a common and recommended way of preparing rice for cooking.
When you do wash the rice until the water is clear it improves the final texture of the cooked rice.
I always wash my rice until the water runs clear and it really does make a difference.
However if you are cooking the rice for a dish that requires a stickier texture such as paella or risotto then you want to rinse the rice less thoroughly.
But for many other dishes or when just cooking rice to eat you should ideally wash the rice until the water is clear but it's okay if you don't do so.
