Following Chef Christine's Strawberry-Rhubarb Crumble

I so wanted to make this strawberry-rhubarb crumble that chef Christine posted, but when I was ready to make this, we just got out of strawberry season. I don't remember why but I had to make cupcakes and used up last batch of fresh local strawberries. I thought I was out of luck till next year. Then last thursday, I was given a second chance.

Dave of Blue Mountain Farms brought ever-bearing strawberries at downtown farmer's market. They looked a little firm but still smelled wonderful. My rhubarb plant is still going strong, we always have lemon at hands, so with strawberries, rhubarb and lemon, I was ready to make this fabulous cake.
Please follow chef Christine's recipe word by word. I made this cake on Monday night after work, after dinner, while fighting my allergies. Hopefully that explains why I used 9 by 9 pan instead of 9 by 13 and the cake looks much thick rather than nice thin as chef Christine had.
Yeon pointing at her 9 by 13 pan: "Dan, is this pan 9 by 13? It looks awfully big." (Please remember I grew up with meters and centimeters and sometimes I still get confused).
Dan: That's not 9 by 13. It is bigger than that. (He has no excuse. He was probably not paying attention).
Yeon: "Okay. I guess I will use a smaller pan then."

I had minor modification as far as ingredients go:

• I had only 1 1/2 cups of fresh strawberries, and my rhubarb stalks are mostly green with red hue, which meant strawberry-rhubarb mixture was going to lack strawberry flavor and color. I added 3 tablespoon of home-made strawberry-balsamic jam to enhance color and flavor.
• When I combined wet ingredients together for cake batter, I added fresh lemon peels from one lemon. I cut down sugar to 3/4 cup in dry ingredient for the cake.

I placed a parchment paper and buttered it so that I can take the cake pieces out easily. I am not sure if it was necessary step or not, but they do come out very easily.

It is a wonderful recipe. Since it requires cooking strawberries and rhubarb briefly, I could try making it with frozen strawberries. And yes, I have a good amount strawberries that I froze this spring. Did I mention my rhubarb plant is still going strong?
