Crepe Craving
So the other night, I had a craving for crepes and my grocery store had strawberries on sale! Score!! I went right home and searched for a new crepe recipe that works better with my crepe maker. As I browsed Pinterest, I found this one that works oh so nicely…
The picture definitely grabbed my attention. Doesn't it look divine?? Maria of The Mother Huddle knows what she's doing in the kitchen. I have to admit though, sometimes I really hate trying recipes from Pinterest…they usually don't turn out or the directions are vague with too many assumptions (ie: add one can–I am wondering what size of can?? sheesh) This picture made me excited to try again.
Making a Ratio Table to Adjust the Recipe
I got the ingredients out and noticed that I had 4 eggs, but the recipe called for only 3. I really didn't want to waste that one egg, so my mind turned to RATIOS! Yes, I set up a ratio table so I could adjust the ingredients to 4 eggs and use that last one.
Here is the original recipe:
1/3 tsp salt
3 eggs
1-1/2 cups milk
1-1/2 cups all-purpose flour
2 Tbsp vegetable oil or melted butter
I needed to find out the measurements for one egg per every ingredient. I divided all of the ingredients by 3 to find that answer as shown in my ratio table below.
After I found those amounts, I added them straight down the columns…making sure to change all denominators into like denominators so I could add.
Finding Equivalent Fractions
So you may be thinking 4/9 of a tsp is kind of a weird measurement! I would agree, but let's reason through how I would add it to the mix. If I look at the original measurement for 1/3 tsp of salt, I could in turn make that into an equivalent fraction of 3/9– which is close to 4/9. I would measure out the original 1/3 tsp and add a pinch more. Now for the 2/3 of a Tbsp, let's use unit conversions here. There are 3 tsps in 1 Tbsp. So you could use the tsp measurement and scoop it out twice. 1/3 Tbsp (1 tsp) + 1/3 Tbsp (1 tsp) = 2/3 Tbsp.
The results were fantastic! Thanks to Maria for making yummy food and sharing with the world. I love this recipe and I hope you'll try it out at home and make a GIANT batch. Math is everywhere 🙂
I am totally coming to your house for dinner! I would love some gluten free, dairy free crepes! 🙂
I love everything about this post! AND…. now I want to try my hand at making crepes!! Thanks so much for linking up with us!
