Method
Prepare the pickled apple: In a small mixing bowl, combine the granulated sugar and boiling water, stirring until the sugar dissolves. Add the cider vinegar and chopped dill, then gently mix in the apple slices. Set aside to pickle for at least 15 minutes.
Prepare the haroset: In a food processor, pulse the almonds and cumin seeds until they form a coarse crumb. Add the remaining haroset ingredients (grated horseradish, chopped beets and dill, pickle juice, lemon juice, and olive oil) and pulse briefly until just combined, retaining some texture. Season with sea salt and white pepper to taste, adjusting the lemon juice and horseradish for balance.
Prepare the matzo tostadas: Break the matzo sheets into large, irregular shards. Heat the vegetable oil in a frying pan over medium-high heat until shimmering. Fry the matzo shards in batches, about 30 seconds per side, until golden brown and crispy. Drain the fried matzo on kitchen paper.
Cook the mackerel: Drain most of the oil from the frying pan. Gently fry the smoked mackerel fillets for about 2 minutes per side over medium-high heat, until warmed through and lightly crisped. Remove from the pan and cut into pieces slightly smaller than the matzo shards.
Assemble the tostadas: Spread a generous tablespoon of the prepared haroset onto each fried matzo shard. Top with a pickled apple slice, then a piece of the warmed mackerel. Garnish with a sprig of fresh dill and a grating of fresh horseradish.
Chef's Notes
- Use good quality smoked mackerel for the best flavor.
- Adjust the amount of horseradish to your preference.
- For extra flavor, toast the almonds before adding them to the haroset.
- When frying, make sure the oil is hot and the matzo is dry to achieve a crisp texture.
Storage
Refrigerator: 2 days — Tostadas best eaten immediately, store haroset and pickled apple separately.
