The word Will is in the present tense. While the word would is is in the future . Will you go to the dance with me? (At this moment ) Would you go to dance with me? ( happening in the future )

The difference is about probability. If you are going to eat it, use "will". If you don't actually plan to eat it and are just speculating, use "would" I do not agree with the other poster. Will is not really for the present.

I think the difference is subtle. Native English speakers like me don't really think about this much, so grammar specialists will be a better reference than native speakers. Here's an actual grammar reference that might help. In this case the difference is between a Type 1 (real) and a Type 2 (hypothetical) conditional. http://www.ef.edu/english-resources/english-grammar/conditional/ In your example case using "will" indicates a higher level of commitment. Because you are using a future tense (will), you are indicating that this is something that probably will happen. "If I go to the dance with you it will be fun." "If I went to the dance with you it would be fun." If you use the first option, it sounds like you are actively considering going to the dance. Like you really want to go to the dance. In the second option, it sounds like a purely theoretical thing that would be fun, but may or may not ever happen. "If I try the new recipe it will be healthier than frozen food." Because you use the future tense here it sounds like you may have already made up your mind up and are ready to go. The key idea is that you have transitioned from considering something as merely an abstract concept to building a potential plan for future action. You haven't 100% committed to going, but it's now a "real" situation instead of purely "hypothetical". If I tried the new recipe it would be healthier than frozen food. Here you are not giving any clues as to whether you plan to do this. But as I said native speakers do not think about this much, so the difference is more of a subtlety and they may occasionally use the two interchangably. Additionally, since you use words like "I suppose I could", and "probably" it adds a lot of uncertainty to the statement, so the level of commitment to actually try the new recipes is not very high in either case.
