"Actually, " said Harry, "Before we dig into the cake, I'm curious about something. Did the bubble create the cake by itself?"
"No, " said Hermione clearly, "Food cannot be conjured by itself, although it can be multiplied if you already have some. It can also be summoned. Most things can be conjured, but food is one of the exceptions. This cake was premade, and the magic of the bubble summoned it here at the appropriate time."
"Who made it then?" asked Harry curiously.
"Tina Creevey!" answered Hermione.
"Excellent, " said Harry happily, "Tina is a wonderful cook and I'm sure this will be a fabulous cake! Tina's Easter ham is still some of the best food I've ever tasted. Before we make short work of this excellent creation, there is something that I think should happen first. Colin, Dennis, since this cake is your mom's creation, I think you two would like to hold it and have me take a picture of it so when it's gone you can have a picture of yourselves holding your mom's creation. Colin, if I could borrow your camera for a minute and a nanosecond, I could take a picture of you and Dennis holding the beautiful cake your mom made for my birthday party before we demolish it."
Colin and Dennis both burst into wide smiles and made their way up to where Harry was standing.
Harry handed Colin and Dennis the cake and Colin handed Harry his camera.
Harry took a couple of pictures of Colin and Dennis holding his birthday cake, a cake Harry now knew their mother had made.
"Actually, " said Colin clearly after Harry had taken those pictures, "I'd like one of you holding the cake with us. Give the camera to Ginny and let her take a picture of Dennis and I holding the cake with you."
"Actually, " said Ginny honestly, "I think Hermione would be a better choice to take that picture. Hermione is muggleborn and understands muggle technology like cameras way better than I do."
So Harry handed Hermione the camera and went to join Colin and Dennis, who repositioned the cake so that all three of them were holding it together and Hermione took a few pictures of Harry, Colin, and Dennis holding the cake together and then returned the camera to Colin as Colin and Dennis let go of the cake so that Harry was once again holding it by himself.
Looking at how the pictures came out, Colin and Dennis just warmly smiled at each other and at Harry and Hermione.
"Harry, " said Colin sincerely, "Thank you for the thought here. Taking these pictures never occurred to me but if we hadn't done so I would have regretted it later. Thank you for thinking of that and reaching out to Dennis and I."
"I knew you might like to have those pictures, " smiled Harry brightly, "Since I did think of it, I made the offer."
"Dennis and I are both very grateful that you did, " said Colin genuinely.
"Mom will be happy to see these pictures too, " added Dennis, "She's really proud of her cooking abilities you know."
"How did Tina become the person to make my birthday cake?" asked Harry.
"The thing is, " explained Hermione, "This cake was just made yesterday. Sirius wanted the cake to be fresh when it got here so it couldn't be made too far in advance. Sirius asked Molly Weasley to do it, but Molly suggested Tina instead. Molly is a great cook of course, but she's a witch and uses a lot of magic in her cooking. Tina is a muggle and can cook only by muggle means. Molly said that there are certain things, especially cake, that come out best when hand crafted by muggle means. Sirius then asked Tina to do it and she agreed."
"I think either one would have been wonderful, " said Harry warmly, "Both Molly and Tina are O in N.E.W.T as far as their cooking goes. But now it's time to dig in! We need to split it into twenty pieces.
Next nanosecond, the cake magically divided itself into twenty completely equal slices. Harry, Colin, Dennis, Fred, George, Lee, Oliver, Ernie, Hannah, Susan, Luna, Katie, Angelina, Alicia, Astoria, Daphne, Tracey, Lily, Hermione and Ginny suddenly each found himself or herself holding a good thick slice of cake in his or her hand.
Everybody's slice was large enough to be a decent amount, but small enough to comfortably hold and eat by hand.
As they all ate the cake, they were totally blown away both by how high quality it was and by how delicious is was. No one said a word as they ate it as they were totally taken in by its yumminess.
But after it was gone, everyone went on for minutes about how yummy and tasty it was. Harry was delighted to have had such a perfect cake at his birthday while Colin and Dennis couldn't stop smiling as pride in their mom engulfed them.
