When I used to go to the market with Grandma, I often begged her to buy raspberries for making this tart.
Grandma's Secret Trick
For raspberry topping, Grandma used seedless raspberry jam to minimize the total number of seeds in each bite. If she couldn't find seedless raspberry jam, she heated the jam in a saucepan over low heat until it melted, then poured it through a sieve, pressing hard to extract the jam. She discarded the seeds, then mixed the jam with the berries.
When Grandma was a girl, this cake was made every June after picking the first wild blueberries.
Gram made this delightful dessert for special occasions and family celebrations.
