I tried "Biscuit Sandwich Coffee" which has been renewed for sale at KALDI Coffee Farm. It has a strong roasted aroma and a strong bitter taste of coffee.
The price is 179 yen (tax included) and the calories are 193 kcal. A sweet made by sandwiching coffee cream with coarsely ground coffee beans between biscuit dough. The beans are further coarsely ground according to the renewal.
By the way, KALDI's original instant coffee "Espresso" is mixed with biscuit dough and cream, and "Mild KALDI" is used for the coarsely ground coffee beans.
The biscuit dough is firm, and it's easy to crack when you raise your teeth. The dough and the cream inside have a coffee scent, but the roast is deep and the taste is bitter. Crushed coffee beans are also added to it, so even if it has a sweet taste, it makes you feel as if you are tasting espresso in the form of sweets.
Of course, coffee is recommended if you want to enjoy a drink together, but if you add espresso, it looks like it's going to come back. How about a cafe au lait with plenty of milk added?
