ソカラット
Socarrat is the rice layer that adheres to the bottom of the pan near the end of Valencian paella cooking. In Valencian it is described as meaning "lightly scorched".

Scope and provenance of the photo
Identification: Identified as labelled in the source. The description is "fondo de paella" (the bottom of the paella). The file name also states socarrat. I opened the image and confirmed a close-up of a dark brown layer of rice stuck to the bottom of the pan, between the yellow rice.

Reading the bitterness
Near the end of Valencian paella cooking, the rice layer adhering to the bottom of the pan is called socarrat. The Acadèmia Valenciana de la Llengua (AVL), Valencia's official language institution, defines it as 「調理する鍋にこびりついたパエリアの米の層」 (in translation: "the paella rice layer adhering to the cooking pan"), and describes the diminutive socarraet as concentrating 「パエリアの本質の味」 (in translation: "the essence of paella's flavor"). This definition uses no specific taste or odor terms such as bitterness or roasted aroma; it is limited to a lexical explanation of how it forms.
The dictionary of the Acadèmia de Cultura Valenciana, another normative dictionary, describes socarrat rice as 「部分的に焦げているが、時にたいへん美味な（molt gustós）」 (in translation: "partly scorched but sometimes very delicious"). Although it uses 「焦げた（cremat）」 (in translation: "scorched"), its evaluative word is 「たいへん美味」 (in translation: "very delicious"), rather than 「苦い」 (in translation: "bitter") or 「香ばしい」 (in translation: "roasted"). This too is a general dictionary description, not one based on a food-science sensory definition.
In food science, a study evaluated paella's heating process with an electronic nose and a trained sensory panel of 9 people. As cooking progressed toward formation of socarrat, 「roasted（焙煎香）」 (in translation: "roasted") attribute intensity increased significantly, while 「burnt（焦げ臭）」 (in translation: "burnt") odor remained lower than for the white-rice control. The paper considers this to suggest that socarrat forms a crust in the pan that prevents the rice itself from burning. However, the panel's rating scale did not include 「bitter（苦味）」 (in translation: "bitter"); this study did not measure bitterness as a taste of socarrat.
The same study detected volatile furan, furanone, and ketone compounds late in heating. Earlier studies report these compound groups as having 「bitter-caramel aroma（苦味を伴うカラメル香）」 (in translation: "bitter-caramel aroma") along with roasted and caramel aromas. However, this 「苦味」 (in translation: "bitterness") is an aroma description based on citations to earlier literature, not data in which people tasted socarrat itself and rated it bitter. The connection between compound identification and bitterness actually perceived by people remains unconfirmed.
