Wash the quinces, cut them in half. Remove core, stem and flower attachment. Dice quinces roughly. Cover with water in a large pot. Simmer covered at low heat for about 45 minutes.
Drain the quinces well. Collect the juice and possibly process it into jelly. Puree the quinces. Reduce 1 kg of puree and sugar at very low heat while stirring constantly for approx. 1 hour until a thick, firm mass is formed
Spread the quince puree into a box form lined with baking paper (approx. 30 cm long) or a flat casserole dish. Dry in a hot oven (electric cooker: 75 °C/circulating air: 50 °C/gas: not suitable) for 3-4 hours or at room temperature for 2-3 days. Leave to cool down
Cut the quince bread into slices. Goes well with Tetilla cheese, Serrano ham and roasted pimientos de padrón (small peppers)
