it doesn't look pretty but it's yummy
Yes, my ube roll is literally broken in several places. I have been trying to make ube (purple yam) roll cake and failed, twice. The first one was too tall and dense for a jelly roll cake and as expected broke into many pieces. Not to mention it was absolutely inedible! I was a little bit suspicious of the amount of flour in the recipe from the Filipino FOOD magazine but went ahead and baked the roll. I should have listened to my gut instinct and reduced the amount of flour by half. The second ube roll (pictured here) is so soft, has a very tight crumb, and delicious but should be spongier/springier because again the cake cracked in several places as soon as I rolled it. The cake is very good though and will probably make it again as a layer cake or cupcakes. The only problem is I can't remember the measurements, silly me.
I am posting the Ube Roll recipe for the cake from the FOOD magazine but not the frosting because I have read a similar recipe online that is proven by users and readers to be unreliable. I am also not able to provide at this time the recipe for the second cake. I used this Pumpkin Roll recipe as a guide, substituting ube which has a different consistency and behavior than pumpkin and forgot to note the adjustments I made. I eyeballed the consistency of the batter as I mixed it. It will not be helpful either because there is something lacking in the (adjusted for ube) recipe to make it spongier and therefore more resilient, maybe eggs or cake flour. Or maybe I need to take ube cake baking lessons. Or tips from experts. Help!:-)
recipe from FOOD magazine
2 cups cake flour
2 teaspoons baking powder
½ teaspoon salt
1 cup sugar, divided
1 teaspoon vanilla
1 tablespoon rum
½ cup milk
1 cup ube, peeled, mashed, and strained
½ cup light corn syrup
7 egg yolks
½ cup corn oil
1 cup egg whites
1 teaspoon cream of tartar
1 teaspoon violet food color
- Preheat oven to 375 degrees F. Butter a 15 x 11 x 1 inch jelly roll pan. In a large bowl, sift flour, baking powder, salt and ½ cup of the sugar. Set aside.
- In a blender combine vanilla, rum, milk, and ube. Blend until smooth.
- Add corn syrup, egg yolks, and oil into the ube mixture. Blend well. Stir into the flour mixture until smooth.
- In a large bowl of a stand mixer, beat the egg whites with the cream of tartar until soft peaks form. While beating, add remaining sugar gradually and beat until stiff. Fold in ube mixture and food color. Pour into pan.
- Bake in the oven for 20 minutes or until done. Turn the cake on a piece of cheesecloth or baking paper and roll immediately. Let cool before filling.
