cooking question!! urgently need to know!?!

Yes you can, it will obviously not have the same taste but will be fine, here on some more subs to look at:

Another substitute for coconut milk is, using one cup of whole milk and adding one tsp. of coconut extract to it. This will replace one cup of coconut milk

Evaporated milk is also known to be one of the best coconut milk substitute. Mix ? cup of evaporated milk with ? cup of water and use as a substitute for coconut milk. This substitute works best in chicken curry recipes.

Another substitute to coconut milk is using unsweetened soy milk. Here is a small recipe that you can try and use the product as a substitute for coconut milk. Take half cup plain soy milk and add one tsp artificial coconut flavor. Add a bit of sweetener and little cornstarch for thickening purpose. The substitute is ready. If you use vanilla, sweet rice milk or sweet soy milk, then do not use a sweetener.

Yogurt can also be used as a substitute for coconut milk. To make, use one cup yogurt and add 1 tsp. coconut extract to it and mix well. You can also use one cup evaporated skim milk instead of yogurt and add 1 tsp. coconut extract to it. Both yogurt and evaporated skin milk will give a thick consistency to the recipe. Use these in same amount as coconut milk is to be used
