There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
An adjective appearing as G. brant “cooked, done” in the Gnomish Lexicon of the 1910s, with the more specific connotation of “overdone”, perhaps due to the influence of the verb G. brantha- “scorch” (GL/24).
Neo-Sindarin: For purposes of Neo-Sindarin I retain the Neo-Root ᴺ√BRATH “cook” along with its related derivatives, so I would retain ᴺS. brant as well. For “cooked” without the connotation of “overdone”, I would use the passive participle brannen of the verb ᴺS. brath- “to cook”.
