Do you use as much paste coloring liquid food in a cake recipe that calls for 2oz of red velvet recipe?

It's impossible to say how much paste coloring to use without knowing the specific red velvet recipe.

Here's why:

* Intensity of the coloring: Different brands of paste coloring have different levels of intensity. Some are very concentrated, while others are more subtle.

* Desired color depth: Do you want a deep, vibrant red or a lighter, softer pink?

* Type of red velvet recipe: Some recipes inherently create a deeper red color than others, requiring less added coloring.

Here's a general guideline:

* Start small: Always add coloring gradually and check the color frequently. It's easier to add more than to take it away.

* Use a toothpick: Dip a toothpick into the paste and add a tiny amount to the batter at a time.

* Mix thoroughly: Ensure the color is distributed evenly throughout the batter.

For best results:

* Test a small batch: Before coloring your entire cake batter, test a small portion to see how much coloring is needed to achieve your desired color.

* Check online for specific guidance: Search for "red velvet cake coloring" online and you may find helpful tips and tutorials.

Remember: Paste coloring is very concentrated, so a little goes a long way. It's always better to start with a small amount and add more gradually as needed.
