Some random stuff - a no-bake pastry cream and raspberry jam "cake" I made from leftover Speculatis cookies (those that look like small windmills) and toasted nuts and leftover "macaron-like" failures. Delicious, delicious cracked failures. Next time I'll watch the cracks early and load them with even more chopped nuts. Other options are (not sure of it will work) - mix in a bit of flour for a even more chewy cookie (I guess it would edge close to a brownie cookie at that point), or chopped dried cranberries for even more chew. And spices!
The cake itself was nothing special (I did not use a recipe, just combined what I had in the fridge), and was better a day after when the cream melded and softened the base which was on day 1 still very crunchy.
Next up is choux - something I actually have real experience in.
