Swirl effect in cremeux cake that is freezable

[Bojana]

I am making cremeux based lemon cake and want to add blueberry swirl effect to it, made with blueberry coulis. What is my best bet to set the coulis so that it is freezable? I have tried with LM pectin but it was still flowing. Maybe I did not use enough pectin or did not get it to set right. 

 

Can someone advise, either on another gelling agent or how to do it right with pectin? I would really appreciate.

Nobody? 

 

Do you think using gelating at 1.5%-2% would work or would it break after thawing, even if the swirls are thin?

I would try a fluid gel made with agar agar.

In theory pectin should work, I have a recipe for a chocolate cake that uses pectin in the glaze and it freezes and thaws very well.  What you want to avoid is syneresis - the weeping or leaking of water when it thaws out.  I just did a google search for pectin and syneresis and it came up with this page, it might help you?
